Renamed the starting level, and now I get Create Export: Failed to load Outer for all my assets

I renamed my level and everything disappeared in my level. I tried to put it back but now everything in my level is unloaded, there’s no details panel for any of them, and when I hit play, my character appears with a camera directly over their head, my bgm plays, and then the character disappears.

I’ve tried deleting the UnrealEngine Folder in local assets, I’ve tried adding the files to a new project. I’ve spent hours going through various steps to fix, and nothing works.
