Now I was in the 3.11 branch so I'm not sure it should be doing a git checkout main. But anyway, the PR was created (in that it opened the "Create pull request" page in the browser, which I clicked to confirm - the PR is here. But if I now try to do the same thing for 3.10, I get

Usage: cherry_picker [OPTIONS] [COMMIT_SHA1] [BRANCHES]...
Try 'cherry_picker -h' for help.
Error: Run state cherry-picker.state=CHECKING_OUT_DEFAULT_BRANCH in Git config is not known.
Perhaps it has been set by a newer version of cherry-picker. Try upgrading.
Valid states are: BACKPORT_PAUSED, UNSET. If this looks suspicious, raise an issue at https://github.com/python/cherry-picker/issues/new.
As the last resort you can reset the runtime state stored in Git config using the following command: `git config --local --remove-section cherry-picker`
I did git config --local --remove-section cherry-picker and tried again, but now I get

It looks like it successfully backported your PR, and while cleaning up and switching back to main (which is expected at this stage) an error occurred. That left miss-islington in an inconsistent state that you fixed with git config --local --remove-section cherry-picker.
I did
git config --local --remove-section cherry-pickerand tried again, but now I get
Not sure about this last traceback though. Maybe just network issues or GitHub being down? It seems you were eventually able to create the PR -- did the same command succeed when you ran it a second time?
Yes, it did - perhaps it was a transient network issue. GitHub seemed generally fine - I was able to monitor the tests, close the issue once they completed etc. I just logged this issue to help fix whatever caused the inconsistent state to occur. You can close it if you don't need it for that purpose.
I ran into errors in the past that required a git config --local --remove-section cherry-picker. Perhaps miss-islington should clean up after herself in case of failure, even though the current design might be intentional in case people want to complete the backport and/or clean up things manually.
