I have been seeing this issue from couple of days and its happening for all our hosts.

I did see some online thread, some cases were clock of the server was off( which is not true in our case)

Runner Version and Platform

Runner version we are using is the latest 2.319.1
OS of the machine running the runner? OSX

Runner and Worker's Diagnostic Logs

Added the runner logs above.

Start with the _diag output and the MessageListener.CreateSessionAsync stack entry, focusing on the OAuth token request returning BadRequest and “Registration was not found or is not medium trust.” Reproduce or trace the failure on the reported macOS runner version 2.319.1, then verify that affected self-hosted runners remain connected without repeating the error.
