how to fix it. also there's about 4 other scene that has the same problem

    piffy11112 res://levels/level5.tscn:168 - Parse Error

    Was that scene, and the others with the same error, created in a different version of Godot?

        Sounds like some resources failed to load. This usually happens if you had some files/textures/etc that were saved as resources in the scene then deleted them after saving the scene. Be careful about doing this as when you lose those resources, your scene doesn't load. Always remove or alter the resources in a scene BEFORE deleting them the files from the editor.

        ok, so i find out i can open the scene with gdscript but i can't open it on the editor
