I imported two 1009*1009 landscapes from the heightmap png, for the optimization, I transformed the landscape to nanite mesh. Then the level crashed, and the level crashed every time I opened it.
I looked it up in the dev community that, the following situation was solved by deleting the wrong static mesh. However in my case, my “Bad Mesh” is the landscape mesh, I don’t know how to remove the landscape mesh if I can not open the level, and I do not know whether this way is suitable for my issue.
Hey all. I fixed up redirectors after moving something and the program crashed. There seems to be a specific static mesh giving me issues but I’m not quite sure what to do with it. Editor crashes before project starts up.

Import geometry with
All good, Actors in outliner connected to imported SM’s in project Contents
Save project and quit UE.
I’ve deleted the offending SM. Try re re-open project again but get the error on a different SM.

I digged out the probable solution:
read the usd cache to get staticmesh and build the staticmesh using StaticMesh::Build
then import the usd
the bad description problem disappeared
