Deleted Project stuck on Gitlab CE

Problem to solve

I’ve this deleted project that is stuck inside my self hosted gitlab. I’ve tried to change its namespace
to my user and now I can not access it.

Everytime I use the web interface, I get a 404 error (address/myUsername/project). If I try to enter to the project as root I get the same error. If I manually put the admin page to that project address/admin/projects/myUsername/project I can get it’s ID, data about disk usage and relative path. But if I try to modify the permission still got 404. I can see that root is an owner of the project.

If I try to use the API with a root personal access token, I can not both GET or DELETE the project by its id, giving me 404.
