When I try to clone my project and set a new name on project then bellow mentioned error is being reported. A path must not be longer then 100 character. but the number of characters of the project name is not longer than 100 characters You can see the problem in the attached video

I encountered the same bug recently. I fixed it by just choosing a file path again. In other words, after typing the new name of your project just click the browse button again and choose a path manually.
