Reproduction steps:

Run the dedicated server (this does not happen on the client)
Cause the CrashReport class (h) to be loaded (for example by using update suppression using the world download from https://youtu.be/IJhZpK-8p54)

Private since using update suppression players can crash the server which would not happen otherwise since the CrashReport is caught and ignored for player actions.
