error: "Something went wrong on our end. Please try again!" When trying to view changes on a repositories merge request migrated from github. (not self hosted)

We get an error when trying to go to Changes, furthermore when we look at the analytics for that project, and look at code reviews, we also get an error. picture of us recieving the error.

This is on, we are not self hosting gitlab.

I have the same problem on 2 projects migrated from github.

I’d go trough support for this, but can’t since i’m a free user.
