Computer refuses to shutdown after updating to v22.0.0.91

I have tried this several times and EVERY time as soon as NS has updated to v22.0.0.91 my computer refuses to shut down.  I have left my system for 10 to 15 minutes each time and it simply will not shut down.  It stays on the "Shutting Down" screen with the spinning circle but that's as far as it will go.

 

Restarting will eventually complete after around 10 minutes but a complete shut down will not / has not completed.

 

Windows 7 x64 SP1

NS v22.0.0.91
