Project ci/cd settings 500 error

When entering the CI/CD settings got a 500 error.
I’m using gitlab.com, and the Request ID: 01FWNFACC3ZEAQ4C9R5CKQ501D

this only happen in a specific repository, cannot reproduce it in other repositories

Sounds like a support ticket with Gitlab is needed…

I did write to support, but no response from them
