Welcome to the forum @GolfBallFromBeefyDie.
Participating in troubleshooting is a very potent way to help learn about GnuLinux and the systems we use.
In order to help users search the forum for solutions, each issue should be contained to its own thread in General Help for a variety of troubleshooting, Hardware Support for hardware specific troubelshooting, Installing Zorin OS for installation help or questions.
@randomPerson, please post your question about GDM3 login in the General Help sub-forum.
