Cups Startup stops Zorin 15.3 Ultimate Gnome Displaying

I have just installed CUPS and now when booting I get some messages related to CUPS before Zorin displays the GNOME desktop and it does not carry on. It is just stuck. I have taken a picture via my phone which is attached.

I just have to use CTRL-ALT-DEL and boot into my Windows Image.

I have tried recovery mode and the options there only installed one package.
So now I am locked out of Zorin image.
I really dont understand this.
