And the 3D sectioning no longer works as expected (see animation of 2d and 3d sectioning working in 2.92 below)

Please only include one issue in a single report. It seems like these are completely separate issues, so please open another report for the "3D sectioning" issue and keep this report for the crash only.

Ok, I'll separate all three issues and add them as separate issues...I'll leave this one to deal with the crash.
