I have had this happen with two scenes by now. These scenes consist of a large tilemap with multiple layers, a player and thats it. The scenes inherit from a LevelBase class I wrote, but that is so simple. that it can’t be the problem. LevelBase just has a open_pause_menu() function and nothing else. Does anyone know why this might be happening?
EDIT: Forgot to translate the message. It says “scene file ‘office.tscn’ seems to be invalid or faulty.”
Version 4.1.2 just dropped, see if the problem persists there (as I’m assuming you’re on 4.1.1) - https://godotengine.org/article/maintenance-release-godot-4-1-2/
If the problem persists, make a copy of your project, open that
office.tscnin a text editor and try to manually remove references to other objects/nodes, saving and trying to open it in Godot, in case the culprit isn’t a circular reference as Zarr pointed out.
