Thanks a lot for reporting. We are aware of this issue - see here, but each report may contain additional useful information.
I’ve now added some more checks and debugging options to the Scissors effect. Please do these steps to help figuring out what the issue is:
- download and install the latest Slicer Preview Release tomorrow (2022-11-27) or later
- hit Cmd+3 to open the Python console
- type this command to enable writing the scissor brush to a file at each scissor operation - replace
/Users/...by a path somewhere in your user folder
slicer.qSlicerSegmentEditorScissorsEffect().setDebugOutputFolder("/Users/...")
- try to reproduce the crash
- if you reproduced it then share (upload somewhere and post the download link) the
DebugScissorBrush.vtpfile that was created in the folder that you specified
