Worked: Most likely a build in the Dec. time frame
Short description of error
The following assert is triggered when attempting to set the visibility of a collection and then deleting it:
BLI_assert failed: c:\users\_removed_\source\repos\blender-git\blender\source\blender\windowmanager\message_bus\intern\wm_message_bus.c:147, WM_msgbus_handle(), at 'mbus->messages_tag_count == 0'
Exact steps for others to reproduce the error
- Load attached .blend file
- Run the script that is currently loaded in the text editor
- Execute bpy.ops.test.trigger_assert() to run that code and trigger the assert
Removing the following line from the script will prevent the assert from triggering: col_bool.hide_viewport = False
This is a reduced repro -- disregard the fact I'm attempting to remove a collection that still has objects inside etc. as the assert happens even if I delete the object.
