Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

Solution 1:

Reinstalling the extension via az extension remove -n ssh && az extension add -n ssh fixed it for me.

Solution 2:

Faced this today and just did a simple extension update to fix it, no removing needed:

az extension update --name ssh

Solution 3:

I manually installed the missing module in the az venv which did the trick for me:

$(brew --cellar az)/2.66.0/libexec/bin/pip install rpds-py
