So I dug into the issue a bit more and it looks like it's a known issue with Godot 4.1.2 for Windows builds exported without debug. It was fixed with Godot 4.2. I uploaded the Debug build for now just so it won't crash on scene change, I'll have to update to 4.2 soon. Thanks for being willing to help though!

Not a problem!
I think our game actually has the same problem, but not consistently for some reason.
I was just playing through ours again earlier and it crashed out just the same as yours did when loading a level. That's the only time it has done it so far though. Good to know that 4.2 should fix that :)
