Error when adding mask modifier

Describe the bug
When selecting the item under mask modifiers

Python: Traceback (most recent call last):
File "C:\Users\isaac\AppData\Roaming\Blender Foundation\Blender\3.4\scripts\addons\Character-UI\operators\use_as_driver.py", line 43, in execute
new_items.append(driver)
AttributeError: 'IDPropertyArray' object has no attribute 'append'

• Blender: 3.4.1

Additional context
I think this error occurred when adding and removing a item. I added the wrong object and removed it from the mask modifier

I had the same problem, a workaround that worked for me was renaming the vertex group / mask modifier and then adding the mask modifier.
