Not really sure where to put this, I finally upgraded today from 2023.2.x to 2023.6.x. I cleaned up a few other things that I needed to remove from YAML but this error doesn’t give me any details as to what actually needs fixed. Any ideas?
I believe that is telling you that it’s the “version” sensor you have configured that is causing the problem.
that has been changed from a sensor with “version” as a platform to it’s own integration:
Remove
- platform: version
from your sensor section in configuration.yaml (or sensor.yaml if you separated sensor into it’s own file).
That whole integration is now in the UI.
That got it, thanks so much! Not sure I would have figured that out on my own. 
Have a fantastic weekend!!
