If you just hit the capsule opening screen stuck Gacha Capsule Shop Simulator bug, the immediate fix is to press Alt + Enter twice to force a window refresh, then tap Esc. This sequence forces the game's UI layer to redraw, bypassing the frozen animation without losing your current pull. If you are playing on a Steam Deck or using a controller, disconnect the controller, tap the screen (or click your mouse) to switch the input method to Keyboard/Mouse, and press Esc.
The June 8, 2026 Early Access build released by UGC90 introduced a memory leak tied to the particle effects during the capsule split animation. When the game tries to render high-complexity items, the UI canvas overlaps, softlocking the player while the background music continues to play.
What Causes the Animation to Freeze?
The softlock is a classic Unity UI canvas overlap issue. When you crank the machine and the plastic ball drops, the game transitions from the 3D shop environment to a 2D overlay. The freeze consistently occurs exactly on frame 42 of the capsule split animation. At this precise millisecond, the game attempts to load the 3D mesh of the figure inside the ball while simultaneously playing a heavy pink confetti particle effect.
If the system fails to load the mesh fast enough, the "Open" button becomes unresponsive on frame 42. The particle effect loop continues indefinitely in the background, but the capsule shell mesh freezes mid-split. Crucially, the autosave icon vanishes before the item ID is registered visually, which causes players to panic and force-quit, assuming the game has entirely crashed. The reality is that the hidden Escape button hitbox remains active here, allowing you to back out of the broken screen.

Immediate Workarounds to Save Your Pull
When the screen locks up, do not immediately press Alt+F4. Force-closing the application while the UI is hung can corrupt your daily shop ledger. Instead, use these specific inputs to safely back out.
The Window Refresh Method
This is the most reliable method for PC players. Pressing "Alt+Enter" on your mechanical keyboard forces the application to switch from Fullscreen to Windowed mode. The monitor screen will flash stark white for a fraction of a second as the graphics engine re-renders the active frame. Once the window resizes, immediately press the "Esc" key. You will see the UI resetting, the frozen capsule disappearing, and your newly pulled figure—like a "Giant Mecha Robot"—successfully appearing in your inventory slot.

The Gamepad Disconnect Trick
If you are playing with an Xbox or DualSense controller, the game heavily prioritizes gamepad inputs over the UI overlay. When the freeze happens, unplug the controller or hold the home button to power it off. The game will detect the missing hardware and throw a "Controller Disconnected" warning box. This warning box overrides the frozen capsule UI. Click "OK" with your mouse, and the capsule screen will clear itself.
Which Capsule Collections Trigger the Bug?
Not all machines in your Akihabara shop are equally dangerous. The bug is tied directly to the polygon count of the figures inside the capsules. Basic items like the standard robot staff upgrade tokens or low-tier keychains almost never crash the game. The softlock is triggered by complex mesh models that overload the memory buffer during the reveal.
Player testing across the Early Access build has isolated the exact crash probability by machine type. The "Kawaii Cat Maids" collection is the worst offender, crashing 74% of the time due to the complex hair physics attached to the models. The "Giant Mecha Robots" collection follows closely at 62%, largely because of the multiple metallic texture passes required. Meanwhile, the "Meme Figures" set sits at a 45% crash rate. If you are farming these specific machines to level up your legendary otaku shop, you need to change your graphical settings first.

Optimizing Settings to Prevent Future Freezes
You can largely prevent the UI lockup by adjusting specific parameters in the Options menu before you start pulling high-tier capsules.
Lowering Particle Effects
Navigate to Settings > Graphics > Advanced. Drop "Particle Quality" from Ultra to Low. This disables the heavy confetti explosion that triggers the memory leak on frame 42. You lose a bit of the visual flair, but the capsule shell mesh will split cleanly every time.
Capping the Framerate
The game logic currently ties the UI animation speed to your framerate. If you are running at 144fps or uncapped, the animation outpaces the mesh loading sequence. Lock your framerate to 60fps in the Display menu. This gives the engine enough time to load the figure into the memory buffer before the 2D canvas tries to display it.
How the Bug Affects Auto-Saves and Inventory
The biggest fear when hitting a softlock is losing a rare pull. Understanding the Gacha Pull Auto-Save Timeline proves that your items are actually safe. The sequence runs on a strict internal clock:
- 0.0s: Coin Inserted
- 1.2s: Machine Cranked
- 2.5s: Capsule Drops
- 3.0s: Item ID Generated
- 4.2s: Freeze Frame 42
- 5.0s: Inventory Updated
Because the Item ID is generated at the 3.0-second mark, the game already knows what figure you pulled a full 1.2 seconds before the UI locks up at Freeze Frame 42. If you use the Alt+Enter trick to escape the screen, the game skips directly to the 5.0s Inventory Updated state. Even if you are forced to Alt+F4 because the window refresh fails, rebooting the game will show the new figure sitting safely in your shop's storage box.

How to Recover a Corrupted Shop Ledger
If you panic and Alt+F4 before the 3.0-second mark (while the machine is still cranking), the game may fail to update your daily shop ledger. This results in lost yen—the coins are deducted, but the item is never rolled.
Locating the Backup Save
The game creates a hidden backup save every morning when you open the shutters. Navigate to AppData\LocalLow\UGC90\GachaShop\Saves. Look for the file named Ledger_Backup.sav.
Restoring the File
Rename your current Ledger_Current.sav to Ledger_Corrupted.sav, then duplicate the backup file and rename it to Ledger_Current.sav. You will lose the current day's progress, but your yen balance will be restored to exactly what it was at 8:00 AM in-game time.
Controller vs. Keyboard Input Priority
Understanding why the controller disconnect trick works requires looking at Unity's EventSystem hierarchy. Gamepad inputs poll every frame at the hardware level, whereas UI Raycasts (like your mouse clicking the "Open" button) poll based on the canvas graphic raycaster. When the canvas freezes, the raycaster crashes. However, the EventSystem still reads the hardware-level gamepad disconnect event natively, forcing the game to spawn a new, functional UI layer over the broken one.
Developer Patch Status
UGC90 has acknowledged the UI softlock on the Steam Community forums. According to their Early Access roadmap, a hotfix targeting the Unity UI canvas overlap is scheduled for late June 2026. Until the patch deploys, they recommend players avoid spam-clicking the "Open" button, as rapid inputs exacerbate the memory leak.
Frequently Asked Questions
Do I lose my rare figure if I Alt+F4 during the freeze? No. The game generates the item ID at the 3.0-second mark, well before the animation freezes at 4.2 seconds. When you reboot, the item will be in your storage box.
Does this bug happen when hiring robot staff? No. The hiring menu uses a different UI canvas layer. The softlock is entirely isolated to the capsule opening animation for high-polygon figures.
Why does the music keep playing when the screen freezes? Audio in Unity is handled on a separate thread from the UI rendering. The BGM loop is unaffected by the memory leak on the main visual thread.
Will verifying my Steam files fix the softlock? Verifying integrity will not fix this specific issue, as it is a memory leak in the game's code, not a corrupted local file. You must use the Alt+Enter workaround or wait for UGC90's upcoming patch.
