Using e-Recovery did you change the Recovery to official when you attempted change community to official? Did you notice, this would involve change in Android version
Android 13 -- T community
Android 12 -- S official
That is an excellent tutorial but not the most up to date, please be fully aware of the main documentation install page Install /e/OS on a Samsung Galaxy S9 - “starlte”.
In view of the possible corruption of Different Build Types and Android version, I think I would Factory reset while you still have that easy option.
