Deleting or renaming objects causes constant crashes

Often after deleting or renaming an object in a content browser or a viewport Unreal starts to crash constantly afterwards. I’m literally afraid to do that now. But because i’m constantly importing objects and textures from Modo i have bunch of duplicated objects like box01, box02 etc. I ended up moving them into separate folder but that is not the best solution.
Can someone recommend me any solution?

here is a crash log:

Hi fleewortep,

I have the same problem since about one or two days. It always happens to me (and I mean every time) when I delet and also when I want to rename an object.
But it happens only in a single unreal project. In other projects the error doesn’t occure.

here is my latest crash log:
