Hey! You should have all your settings in the backup file Ghost made before the migrations (in ./content/data)
We weren’t able to reliably reproduce this locally, but believe it may have been related to a settings cache issue, if you roll back and restore your settings, you should be able to upgrade to the latest release 3.22.1.
If you continue to have issues, it would be great to get some more information about your install/data to try and reproduce locally
