Thanks for the tip Tim, I found this major bug tracker today, and that could be a reason for our errors in the quiz questions tab?

Tim, I have a question about the DB schema, is it possible to check whether data/relations have become corrupted in the Moodle database?
I checked the tables with the mariadb-check routine but the result was no errors. It is difficult to solve corrupted data in courses without knowing how to repair the corrupted data/relations.

I can look at the data directly but unfortunately I don't have enough knowledge of Moodle's DB schema.
Hi Tim,
Is it possible to solve this problem or is the course content corrupted? Could this be the result of a backup restore that didn't
end well? We can't use the courses now anymore and that's a problem for the teachers working on these courses.

We are using Moodle 4.1.9 and in several courses (also restores from backups) we have problems to open the Question tab in a quiz. This is the stacktrace of one the courses with these problems:
