Hi there! I see that you’re trying to open Antstream Arcade via Epic Games, but the app opens and then immediately closes. Let’s get this sorted out for you.

To start, can you tell me:
- Whether the app crashes immediately on launch every time?
- If you’ve tried restarting the computer or Epic Games launcher recently?
- If you’ve checked for any app or Epic launcher updates?
- Whether this happened suddenly or after some changes like a Windows update or new software installation?

Meanwhile, here’s a step-by-step approach we can try:

1. Restart Your PC and Epic Games Launcher
Sometimes, a fresh start clears temporary glitches.

2. Check for Updates
Open Epic Games launcher, check if there are updates for the launcher itself and Antstream Arcade, then install any found.

3. Verify Game Files via Epic Games
- Open Epic Games launcher
- Go to your Library
- Click on the three dots next to Antstream Arcade and select “Verify”
This will check for corrupted or missing files and fix them.

4. Disable Fullscreen Optimization (since you're on Windows 10)
- Find the Antstream Arcade executable in the Epic Games directory
- Right-click > Properties > Compatibility tab
- Check “Disable fullscreen optimizations”
- Click Apply, then OK

5. Clear Epic Games Cache
- Close Epic Games completely
- Press Windows+R, type %localappdata% and hit Enter
- Find the folder named EpicGamesLauncher and delete the Saved folder inside

6. Run as Administrator
- Right-click on the Antstream Arcade shortcut or executable > Run as administrator

If after these steps the problem persists, there might be a crash log we can examine or it might be related to your system environment interacting with the Epic version of the app. In that case, I can help guide you through collecting logs or submit a ticket to Antstream support for a deeper look.

Does that sound good? Let me know what you’ve tried or any other symptoms you notice!
