It's no worries, these kinda' platform specific issues are just always a headache to debug
Sorry to hear you're still having issues. Is your PC particularly low end? I wouldn't have thought the game would be that performance intensive. Other than that, perhaps it's a problem with Godot on Windows 11? Someone else was also reporting problems from a Windows 11 device...
Sorry, I know this isn't a particularly helpful answer, but I can't really think of another reason for it 😔
