404 after importing project by repo URL

Summary

I wanted to import a Project from Bitbucket Cloud, unfortunately it always says that the namespace is already taken. (I tried multiple projects).

After that I tried to import a project using the repo URL. This seemed to work first, but I cannot access the project page since I am getting a 404. I also can't delete it, since I cannot access the project page.

Steps to reproduce

1. Import project by repo URL
2. Click on project link in the list of projects
3. The 404 appears
