Broken level files

Godot Version

4.2.1

Question

Hi everyone, I was working on levels as usual, after working I closed the engine, but after I opened it again it says the level files are corrupted. What happened and how to fix it?
Error code: Failed loading resource: res://Scenes/LVL04.tscn. Make sure resources have been imported by opening the project in the editor at least once.

try reload current project, if that cant, then you want to revert to older version for your game
