Import in progress takes forever and can't be cancelled

Summary

I wanted to mirror my repository from gitlab to github but I missclicked and made a pull mirror repository action. And now I can't access homepage of my repository, gitlab redirects me on import page. I would like to know if it was possible to cancel the import.

Steps to reproduce

(How one can reproduce the issue - this is very important)

/settings/repository -> Mirror a repository in pull direction and delete it immediately

What is the current bug behavior?

Repository is saying "Import in progress"

What is the expected correct behavior?

I would just like to use my repository without importing loading
