Removing user with Gitlab Rails crashes the page member of Groups

Hi All,

It’s my first post on the forum! :smiley:
I have setup a gitlab CE for me and some friends as a Docker Compose service. I had to remove a user so I used gitlab rails to remove it. However he was in a Group and now when I try to access the group’s member page it crashes with error 500 :frowning:
Any idea how can I debug this? Remove the user from the group, recreate the user…
