Stuck at login after entering password

I downgraded my Mojave Hack to High Sierra so I could use my GTX1070. It’s been working very well for about a month but yesterday I booted into Windows (changed the boot drive to my other SSD). After I changed it back I can’t log in to my user in HS - I am able to login as a guest user but after I enter my password for my user it freezes... any ideas? Windows might have installed an update, could that be the issue?
