Git clone $any-repo fails with fatal error

git clone does not work for any repo.
My pc is macOS Catalina. I have deleted all the github entries from keychain.

This is one example but the output error messages are all the same.
Even I can not clone my own directory.

$ git clone --verbose “https://github.com/areslp/matlab.git
Cloning into ‘matlab’…
fatal: remote error:
path/to/repository is not a valid repository name

Don’t include in the remote the trailing .git! i.e. just:

https://github.com/areslp/matlab
