How to downgrade from BETA version? (pypipip)

Anki was working without problem…
However, when I updated now it does not want to open.

I’m using this version.

Version 2.1.56 BETA was working great.

But now I switched to version 2.1.57 BETA it has this error:

Traceback (most recent call last):
  File "/home/cantalupo/.local/bin/anki", line 5, in <module>
    from aqt import run
  File "/home/cantalupo/.local/lib/python3.10/site-packages/aqt/__init__.py", line 40, in <module>
    import anki.lang
  File "/home/cantalupo/.local/lib/python3.10/site-packages/anki/lang.py", line 12, in <module>
    import anki._backend
  File "/home/cantalupo/.local/lib/python3.10/site-packages/anki/_backend.py", line 14, in <module>
    from anki import _rsbridge, backend_pb2, i18n_pb2
ImportError: libpython3.9.so.1.0: cannot open shared object file: No such file or directory

If pip uninstall doesn’t work, you may need to manually clean the files up. Not sure what the problem is there; the 2.1.57 beta successfully imports into a recent Python version here.
