Blender Version
Broken: version: 2.90.0, branch: master, commit date: 2020-08-31 11:26, hash: rB0330d1af29c0
Worked: 2.83.5
Behavior changed in rB164f40c50a05

Short description of error
While Weightpainting a model rigged with bones, if you try to select another bone, while you do it, it exits the Weightpaint mode, 3d model goes to Object mode and the new bone is not selected.

Exact steps for others to reproduce the error

  1. Open the Weightpaint rigged.blend attached with Blender 2.90
  2. Select the armature and press TAB to activate Pose Mode
  3. Select the head bone
  4. Select the 3d model and press TAB to activate WeighPaint (If you can't select the 3D model, go to Edit > Lock Object Modes and deactivate it)
  5. Try to select the jaw or neck bone to see the weights applied to it (my case is CTRL + LMB) <-- At this point you get the bug, you dont select the other bone and set active the armature and weightpaint mode closes to Object mode.

This report is missing:

  • Last version that worked.
  • Exact steps to redo the error.
  • A blend file (unless there are simple steps to redo this from the default startup).

Where is this Weightpaint rigged.blend from? Can you upload this here?

srry, uploaded right now, the blend file is uploaded.

Is there any problem with this bug? it's still in "Needs Information from User" but I think it's everything here.

Can confirm the behavior changed.
Will check what happened here -- and for what reason (but also not really sure why you select with Ctrl+LMB?)

Philipp Oeser (lichtwerk) changed the subtype of this task from "Report" to "Bug".

Behavior changed in rB164f40c50a05: Fix T79503: Selecting edit-bones while holding Ctrl crashes.

Will confirm since this seems like an unintentional change.
