I was setting up lighting for a scene I just finished putting together. I walked away, came back and Godot and it was gone. Thankfully I had saved right before, but opening the project crashed on open with no message, then the 2nd time said a similar error to this one with a bed mesh.
So I removed the bed mesh from the project then loaded, but forcing the other scene (which is my main map right now, basically) to open sometimes causes this error, or just no error at all.
I tried running as admin, making a new bed mesh and replacing the old one to open the map scene, but it still does the same thing every time.
Here's the error:

Is this scene just gone now, or is there some way to save it? I literally just finished setting it up after weeks of putting assets together.
Edit : I tried using the text editor to see if anything was wrong with the scene, put it in a new project and got an "error cannot open scene", and that other error is a memory error? I'm guessing it was saving the scene or something and crashed, corrupting it, that's my best guess. Let me know if you have any ideas.
