After updating to nextcloud 15.0.6, unable to see "Everyone" in users section

After updating to 15.0.6 from 15.0.5, on my users page when it says “Everyone” I am unable to see any users. I get the following error: An error occurred during the request. Unable to proceed.

None of my user accounts show up, after the update it prompted me to change my database so I can allow support for Emojis etc. Any ideas how I can fix this?
