Short description of error
Blender crashes while in Point normals to target mode on Ctrl+Z or Tab press

Exact steps for others to reproduce the error

  1. Enable Auto Smooth for a mesh object (Properties/Normals tab)
  2. Go to Edit Mode for this object
  3. Select Mesh/Normals/Point normals to target (or Alt+L)
  4. Press Ctrl+Z on keyboard (or Tab)

Notes:

  • Does not reproduce if Point normals to target was confirmed or canceled (Enter/PadEnter/LMB or Esc/RMB)
  • Reproduces if any action (or combination of actions) was selected between steps 3 and 4 (point to mouse/pivot/object origin, reset normals, etc.)

I have re-triaged this report and can not reproduce it.
Can you please check if this is still an issue in latest build?

⇥ is leaving editmode, that is also reported here T68159: Mesh->Normals-> Point to Target crashes when switching out of editmode
Ctrl + Z will also leave editmode in certain situations (like the repro step provided here)
