Exception when launching editor after switching from 4.20.3 to 4.21.1

When I launch editor via epic games launcher there is just crash when I launch editor through visual studio it stops with exception at PxU16 PMaterialCount = PShape->getNbMaterials(); (Look at screenshot)

Is there something I did wrong or that’s just a bug?
