Samsung S7 Oreo Update, NO home screen, HELP!

I just updated my S7 to Oreo. As soon as the phone rebooted, it keeps saying “Samsung Experience Home has stopped working” and either asks me to reload it or close it... and I have no home screen, no app, nothing. Just my background pic and the status symbols at the top. I literally can’t do ANYTHING! What should I do? How can I reset the phone?
