Problem with post revisions after updating to 2.8.6 stable or 2.9.0.beta7

Hi guys,
unfortunately I wasted time in this thread…

So I just updated to latest build and still have the issue as well.

I tried to run this but guess my setup does not allow me to help here:

I have it running inside docker / postgres.
Is there anything else I can do to help you with this?

Those are my used plugins
