Update 4.6.9.3 and can no longer send 'push notifications' ?

I allowed the automatic upgrade.
It totally hosed my Windows 10 Pro server.
The UI freezes and locks up with the spinning hoop and "Blue Iris is not responding..."
I can't even close BI.

ARGH

I had to revert to v4.6.2.1 but it's still slow and hoopy.
"Blue Iris Video Security ...is not responding"

I was thinking that a Windows Update messed it up, but the one I got on 02/21/2018 is the Microsoft HIDClass 9.9.108.0 driver update.
I tried twice to do a System Restore but it fails.

Gonna hafta to reinstall Windows 10.
 
I had contact with support blue iris. They told me that google changed something. The only way to resolve this issue is to install the latest update.
