My Unreal Project will no longer open and goes straight to a crash. Help please

Not sure what I did, but I saved my project and closed it, then no more then 15 minutes later when opened again I get the following error. Is there any saving this? I would be losing a fair amount of work. I did some organizing of my assets in the content explorer idk if I did something wrong there?

EDIT: Okay I was able to figure it out, I had moved the Level file and its HLOD Layers and I guess Unreal Engine doesn’t like that. I deleted the copied files and put them back where they should. The project opens and works fine but upon opening I get a punch of caution messages like this one, is there something I could do to stop these errors?

“CreateExport: Failed to load Outer for resource ‘ActorFolder_UID_3A8CE5DF-4B86958F-6984408C-CDCC8CCD’: Level /Game/Map/Map.Map:PersistentLevel”

Original Error Message:

Try these things first:

  • double check your Project Setting > Maps & Modes > if everything is set properly if you have change your level asset location.
  • in file explorer>your project folder> delete the folder: “Intermediate” and “DerivedDataCached”
  • In your content browser, do fix redirectors:
