Blender 2.90
Windows 10
Blender crashes when using Edge > Offset Edges > Extrude.
Crash doesn't occur when going that way:
Edge > Offset Edges > Move (or Offset) and only changing method to Extrude from Adjust Last Operation window.
A possible workaround is to go to Add-on Preferences and uncheck INTERACTIVE.
It will not crash then.
