[Python] I updated to Spyder 6.05, and my kernel is now not loading

I have been regularly updating my Spyder (it is on a Windows), and today I updated Spyder to the newest version, and got the following error in the Console saying that it could not load the Konsole:

Traceback (most recent call last):
File "C:\Users\user1\AppData\Local\spyder\Scripts\mamba‑script.py", line 6, in
from mamba.mamba import main
File "C:\Users\user1\AppData\Local\spyder\Lib\site‑packages\mamba\mamba.py", line 46, in
from mamba import repoquery as repoquery_api
File "C:\Users\user1\AppData\Local\spyder\Lib\site‑packages\mamba\repoquery.py", line 12, in
def _repoquery(query_type, q, pool, fmt=api.QueryFormat.JSON):
^^^^^^^^^^^^^^^
AttributeError: module 'libmambapy' has no attribute 'QueryFormat'


Is this a bug in Spyder that I should report, or should I be updating my Python version?
