Whenever I launch Git CMD and try to do this specific cmd it doesn't work at all. It just freezes.
Heroku login
After I do the command, it says "The system cannot find the file path specified" When Heroku login just asks me for my email and password.
I have tried to re-install already.
This has nothing to do with git; you're trying to use the heroku command line tool, but Windows can't find it in your PATH.
If you installed the CLI tool and it had something about being added to PATH, try restarting your computer. Otherwise, learn about PATH and how to add stuff there.
E.g. Adding directory to PATH Environment Variable in Windows
