I'm getting the following error:
File "/home/ron/rzg2l_bsp_v1.3/poky/bitbake/lib/bb/compat.py", line 7, in <module>
from collections import MutableMapping, KeysView, ValuesView, ItemsView, OrderedDict
ImportError: cannot import name 'MutableMapping' from 'collections' (/usr/lib/python3.10/collections/__init__.py)
and Googling revealed that flask has to be >=2.0, so I did
$ sudo pacman -Syu python-flask
which installed version (2.0.2-3)
which did not resolve the issue. Further searching revealed that babelfish needs to be upgraded too, so I did:
$ python3.10 -m pip install babelfish -U
which showed me:
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: babelfish in /home/ron/.local/lib/python3.10/site-packages (0.6.0)

but I'm still getting the same error. Can anyone tell what else I'm missing?

You need to import collections.abc
Here the link to doc
>>> from collections import MutableMapping
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name 'MutableMapping' from 'collections' (/usr/lib/python3.10/collections/__init__.py)
>>> from collections.abc import MutableMapping
Deprecated since version 3.3, will be removed in version 3.10: Moved Collections Abstract Base Classes to the collections.abc module. For backwards compatibility, they continue to be visible in this module through Python 3.9.

You have to import using
from collections.abc import MutableMapping instead from from collections import MutableMappingmechanical_meatPermalink

side note: using the OS to upgrade Flask might be operating on a different version of Python than the 3.10 you're using. that might be the only version you have, but i think unlikely.
