Python 3.11 incompatability Framerate error: for field F23_98 is not allowed: use default_factory

Receiving this error in Python3.11.

  File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/dataclasses.py", line 1210, in wrap
    return _process_class(cls, init, repr, eq, order, unsafe_hash,

ValueError: mutable default <class 'vtc._framerate.Framerate'> for field F23_98 is not allowed: use default_factory

Works fine in Python 3.10. Looks like something may have broken in 3.11.

Interesting. Will need to take a look. Sorry, I am just seeing this notification now.
