ytmusicapi: get_album() results in KeyError: 'frameworkUpdates'

Have never had issues before (aside from my auth key going expired) until recently. Most of the other api calls work fine such as : search() get_liked_songs() ect, so i assume my auth key is still valid. I only see this issue with get_album().

To be sure my problem is repeatable, i was able to replicate in. a fresh python 3.9 venv with the following

$ python3 -m venv ./test
$ source test/bin/activate
(test) $ pip install ytmusicapi --upgrade
(test) $ python

…then in the python console

(note i tried other browseId values for get_album() like get_album("MPREb_4pL8gzRtw1p") from test.py

>>> yt.get_album('MPREb_EW11k5ujKg4')

any ideas? I saw some closed issues with similar errors, but i think this issue recently popped up, my code worked fine about a month ago
