2 days of work gone?

I have been working on a terrain landscape for 2 days now. Had camera animations in it and a lot megascan models etc. Now I wanted to activate a plugin called “Movie Quee” I had to restart UE 5.1. Now after restarting everything seems to be gone.

I get this warning: Fixed up deleted layer weightmap.

I didn’t delete anything.

Also when I go to Foliage section. There is only one item with 14.1k instances. I had like 40 different foliage assets in that list. Only 1 shows up.

I hope all the hard work can be fixed somehow. Hope someone can help me out.

This is the console log:
