Redmine

When I try to create a new version in the projects roadmap I get this error:
"Status is not included in the list"
and the version is not created. Sreenshot attached.

My installation:

  Redmine version                4.2.6.stable
  Ruby version                   2.5.9-p229 (2021-04-05) [x86_64-linux-gnu]
  Rails version                  5.2.8
  Environment                    production
  Database adapter               Mysql2
  Database                       MariaDB 10.5.16

I removed all plugins for testing and did a fresh installation using the existing database, but the error persists.

However, if I create a new database the error is gone and the version gets created successfully.

There is no error in the production.log to see:

Anyone any idea, how to resolve this. Seems it's something wrong in the database, but I've no idea where to look.
