Github invalid path error - unable to clone repository into GitHub Desktop

I am new to GitHub and trying to clone my team's repository into my GitHub Desktop. However, I get the following error.

Cloning into 'C:\Users\prisc\github\sex-bias\sex.bias'... remote: Enumerating objects: 809, done.
remote: Counting objects: 100% (29/29), done.

Resolving deltas: 100% (340/340), done. error: invalid path 'Icon?' fatal: unable to checkout working tree warning: Clone succeeded, but checkout failed. You can inspect what was checked out with 'git status' and retry with 'git restore --source=HEAD :/'

Any ideas what is happening? I've also tried cloning from the terminal and get the same error.

Thanks, Pri
