Customtkinter v5 crashes TkinterMapview

[felle9900]

Today I updated my version of Customtkinter to v5, but now my TkinterMapView crashes my app. It worked fine yesterday before I updated.

I get this error:

File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/customtkinter/windows/widgets/core_widget_classes/ctk_base_class.py", line 153, in cget
    raise ValueError(f"'{attribute_name}' is not a supported argument. Look at the documentation for supported arguments.")
ValueError: 'bg' is not a supported argument. Look at the documentation for supported arguments.
