Short description of error
The "Make Single User" seems to cause edit mode to crash when executed under very specific circumstances.

Exact steps for others to reproduce the error

  1. Open default startup file
  2. Open search menu ("F3")
  3. Find and run the "Make Single User" function
  4. Select the "Selected objects" option when prompted
  5. In the floating left bottom corner options box, only select the "Object Data" option and nothing else
  6. Duplicate Linked the default cube ("Alt+D")
  7. With either of the two cubes selected, open the search menu, and run the "Make Single User" function again with the same parameters
  8. Press TAB to enter edit mode
  9. Blender should crash

Deselecting and re-selecting before step 8 avoids the crash.
