yep, weird ugly things are happening here… probably due to mixing undos. @Campbell Barton (campbellbarton) think that one is for you?

2.8 have changed since this report was made.
The crashing are still happening in this very specific and odd situation but to reproduce the error now it has to be clarified in the steps above that you change to Sculpt mode through the "object interaction mode" menu at the up left corner of the screen.

The crash do not occur when reproduced in the sculpting workspace!

Some fixes have been made in this area recently so this may have been fixed too.

Closing, report a new bug with spesific steps that crash.
