Based on how you phrased that, it's important to note that you can't downgrade a database to an earlier version, i.e. once you've upgraded to 23.3, you can't go back to 22.11. You'd have to roll back to the 22.7 version (i.e. restore it from backup) and upgrade that first to 22.11 and then to 23.3.
If that's what you did, are you seeing this on 22.11.9? Are there other errors in the logs or during startup?
