Inconsistent query result: Field user is required to return data, got `null` instead

Describe the Bug

Users are unable to access the teams page. The following error message appears:

It seems that database migrations may not have been applied. We do see other errors as well hinting that some website events aren't being inserted. This instance has been running for months and we have not tampered with the database or Umami itself.

Database

PostgreSQL
