Web IDE not loading anymore 'Branch master was not found in this project's repository.'

I installed a fresh version of the gdk today, but it seems like the Web IDE is not working at all in the gdk anymore. Everytime I try to load it, it shows an error message with Branch master was not found in this project's repository. When I click on Create branch, a new error comes up that says An error occurred creating the new branch..
