panic medic boot

My mac keeps shutting off and the touch bar doesn’t work. Here’s what i got in the report:

panic(cpu 1 caller 0xfffffff025aef578): userspace watchdog timeout: no successful checkins from dfrd in 180 seconds

dfrd has not exited since first loaded

service: dfrd, total successful checkins in 230 seconds: 4, last successful checkin: 180 seconds ago

service: remoted, total successful checkins in 220 seconds: 22, last successful checkin: 0 seconds ago

service: bridgeaudiod, total successful checkins in 230 seconds: 23, last successful checkin: 0 seconds ago

service: logd, total successful checkins in 230 seconds: 22, last successful checkin: 0 seconds ago


What can I do and how can i fix this?
