Yes, I found it in the configuration file. No, it does not run in Godot 4.0 and fails to compile with about 85 errors. Most of them are trivial renames, like Texture -> Texture2D, or "missing partial modifier on declaration of type", however some of your core classes also seem to be missing methods / suitable overrides. I assumed that since this was mostly a simple refactor (plus the config file) that the old version was uploaded.
If that was not the case and is indeed the correct version, then it no longer compiles on Godot 4.0
