Why does the editor sometimes crash when editing geometry?

I created cone brush on my level.
and I moved its vertex position by geometry edit.
usually it works well. but sometimes it cause crash.

even I cannot open the project.
maybe it saved on crash state.

how can I recover it?
and epic know this issue?

(I submitted the report)

Hello! I would like to include my experience of UE4 crashing after using the geometry editing tools.

This is what my crash message gave me:

I use the editing tool to move a wall. Then I went back to “place” mode, and clicked on the model. Thats when it crashed. I was able to reproduce the crash 2 times in a row after experiencing it for the first time. On my 4th try, it didn’t crash.

Hope this report helps! I sent my crash report aswell!

Any sort of macgyver solutions would be appreciated! :smiley:
