Labels and metrics lookup was disabled in data source settings_b

<Grafana v 9.0.2 on RHEL 7.9

Recently, ALL of my dashboard queries have in bold yellow the message “Labels and metrics lookup was disabled in data source settings.”

And all queries, ragardless if they are disabled or enabled (eye icon) indicate disabled.

I made no changes to data source - it’s the same (prometheus) that I’ve been using for over a year.
Why is this, what does it mean, what changed, and how do I remove this message?

Thanks!

bumping this issue as it’s also been in github for weeks.
