Pipelines broken since update to 13.8 | NoMethodError: undefined method `keep_latest_artifact?'

Summary

Since upgrading to 13.8, Pipelines are broken as there seems to be some error related to the keep_latest_artifact setting. Pipelines will not run from commits or triggers, also manually starting the pipeline will not work. Clicking the button has no visual effect on the CI. If I go to I see the error message "There was a problem fetching the keep latest artifact setting." and updating the setting also does not work.

I already tried gitlab-ctl reconfigure, gitlab-ctl upgrade, gitlab-ctl restart, gitlab-ctl revert-pg-upgrade, gitlab-ctl pg-upgrade. All run without errors, but don't fix the issue.

Last resort would be from a backup from before the upgrade to 13.8, but I would prefer not losing data/changes since then.

Steps to reproduce

Upgrade gitlab ce from 13.7.latest to 13.8. via apt-get upgrade.

I looked for a related database migration and made sure it ran, and logs show it being fine:

== 20201204193952 KeepLatestArtifactProjectLevel: migrating ===================
