Galaxy S7 Oreo update - now no home screen, help!

So I just downloaded the Oreo update on my GS7 and now I have no home screen & no app buttons. Just my background picture and the status bar at the top. What the hell am I supposed to do now?

 

I keep getting a “Samsung Experience Home keeps stopping” error and either reopen, close or send feedback options.

 

i have rebooted the phone and that didn’t do anything. Can anyone help me?
