an entry at stack exchange by user pion suggests:


dfrd is the Dynamic Function Row Daemon, i.e., the piece of software that talks to the Touch Bar. The fact that your panic signature indicates that dfrd has not sent an "I'm alive!" message in 3 full minutes coincides perfectly with the fact that your Touch Bar is nonfunctional.



You should run diagnostics, AND get your backups completely and utterly up-to-date. You may need service, and Apple does NOT promise to return the data on your boot drive intact. They make you swear you have a backup.
