Greyed Out Tiles / No Data on Tiles since upgrade

  • What Grafana version and what operating system are you using? - CentOS & 8.4.4

  • What are you trying to achieve? - Upgrade to 8.4.5+

  • How are you trying to achieve it? - Normal Upgrade

  • What happened? - When we upgrade to anything above 8.4.4 the dashboards all lose their values and the tiles all become Grey. I can go into a tile edit, and can see the value, save and refresh the page and its gone again.

  • What did you expect to happen? - normal tile behaviour

Screenshots below of what happens:

Any ideas?

Update - I went back to version 8.4.4 and restored the dashboard to yesterday and all the tiles/panels began to work.

I believe theres an issue with version above 8.4.4 causing my panels to not work?
