Project accidental damage

When I was using the Gitlab virtual machine, an accident caused a software pool on the system to be damaged. But I can see this project on the Gitlab web side, but after clicking it will prompt 404 (the website can’t be found). At the same time, when I use git to push locally to the server, I also prompt that the push failed. I want to know how to delete this software pool. Now that the Gitlab server is running normally, I just want to remove the corrupted project, but since my web side is corrupted, I can’t do normal operations. Is there a background operation to help me remove this annoying display?
