Hello, thanks for the report, but I'm not sure if we should disassemble the addon. Please report the bug to the author of the addon, or simplify it to a single file with as small a size as possible.

Yeah, I am the author of this addon. I tested it for a while to find what code crash the blender. I just create a one-file-version addon to show this error @mod_moder

Steps:

  1. Please open gizmo crash.blend
  2. Run the script, you can see some difference in 2 views when playing the gizmos
  3. Merge 2 3dView area, blender crash

using self.gizmos.clear() instead of removing each one by separate removes the crash, don't know if it works for you

executing the script already gives a heap-use-after-free in debug builds:
seems like we are calling GizmoGroup_gizmo_remove and then still accessing stuff that was removed

yes it works.Seems this error happended when delete gizmos in for loop.
I have lots of gizmos for different usages in one gizmo group. Should it be separate them into different groups to prevent this error?

The problem was using self._rotate_gz.clear(), couldn't say exactly why (i think it tries to freethe memory of the gizmos objects, but they are already cleaned on self.gizmos.remove(gizmo)), but using intead self._rotate_gz = dict() solves the issue. You can use also arrays, but array.clear() will make same issues that dict.clear() does.

See video
