Could you please share /Enemies/enemies.collection and /player/Projectiles/pizza.go here (zip file)? My guess is that there is a character somewhere in the file which our build system doesn’t like.
Are you using Windows?
Have you edited the files outside of the editor at any point?
Sure, or you could just zip up those two files. In either case, attach the zip archive here. If you share the full project then please make sure to exclude the “build”, “.internal” and “.git” folder.
I actually don’t spot a problem in the files you shared… btw you shared pizza.go and a .script file, not enemies.collection. If you are comfortable to share the entire project please do so!
In the image above you’ve already assigned a box shape. You can’t use an image like that as a shape. You have the same in pizza.go and some other places. Remove the filename from the Collision Shape field and it should work.
