Could not resolve assembly error

[Enkidu93]

Recently saw a new error on the machine job server:

fail: Hangfire.AutomaticRetryAttribute[0]
      Failed to process the job '667c0900463c96428ae5ed9b': an exception occurred.
      System.IO.FileNotFoundException: Could not resolve assembly 'SIL.Machine.AspNetCore'.

@ddaspit, any clue as to what could be causing this?

Did the server restart right before or after?
