Dropouts/freezes after Windows 10 update to 2004 build

Dear Community,

I have successfully upgraded both machines which are in use with Audirvana recently. Since then I experience reproducable dropouts when listening to Tidal MQA streams. Upgrading to latest Audirvana version available today and increasing buffer size did not help. I use a Pioneer N50ae via Upnp which was working without flaws before the windows upgrade. No other changes have been done to the system. I did not yet re install Audirvana. Still need to test playing through DAC USB connection…

Any chance someone did come across the same issue and found a solution approach ?

Many thanks & BR, Lars
