IPhoneXS

Last night my IPhone turned off and said I needed to connect to my Laptop/ITunes. On ITunes, it mentioned I needed an update to solve minor bugs. Once my phone turned on, FACE ID was not working. I went into Setting and disabled to setup again. I am not having any success. I keep getting the message....raise your phone, lower your phone. I checked online and I see posts mentioning a restart solves this. This is not the case for me. I have restarted and no success after multiple tries. What step am I missing?
