WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].


It's a known issue in PMM 8.1.


Please update your PMM environment to version 8.5 or newer.

If installing the update isn't possible at this moment, as a workaround, you may install SCCM Console, PMM Console extension to the WSUS server, and reconfigure PMM Software Update Point.
