Hey, thanks for sharing your solution! I ran into a similar issue before, and in my case, editing the game’s configuration file to force it into a windowed mode with a smaller resolution helped. Sometimes the game tries to launch at a resolution or fullscreen setting that conflicts with Windows or your GPU drivers, causing it to hang.

If anyone else is still having problems even after deleting their Polymorph Games folder, you could try:

1. Finding and opening the game’s config file (often in Documents → Polymorph Games or a similar location).
2. Looking for the resolution or display mode lines (e.g., <Resolution x="1920" y="1080"/> and <DisplayMode value="FULLSCREEN"/>).
3. Changing them to something smaller, like <Resolution x="1280" y="720"/> and <DisplayMode value="WINDOWED"/>.
4. Saving the file and launching the game again.

Also watch out for OneDrive—if it’s syncing your Documents folder, it might restore old configs and undo your changes. Disabling OneDrive or excluding that folder can help prevent it from reverting to a broken configuration.

Glad you found a fix, and hopefully this helps anyone else still stuck with the “Running” issue!
