Kernel crash and blank touchbar

Can anyone help me troubleshoot.

I have the below error and the macbook shuts down within a minute or two of being turned on. The touchbar is black.

It's fully updated and I had the same error in safe mode.

panic(cpu 1 caller 0xfffffff01b59c2d0): userspace watchdog timeout: no successful checkins from dfrd in 180 seconds

service: dfrd, total successful checkins since load (1730 seconds ago): 155, last successful checkin: 180 seconds ago
