The only thing I ran across after the 1809 update was I had to reset my PC audio options. Stereo Mix for default recording device and Speakers for default playback device. I had to reauthorize a couple of plug-ins but that happens on any update such as this. No Sonar/Studio One 4.1 or MOTU issues.
The Insider versions are a different story. Lots of people having problems installing the update for the latest Insider Build 18262.100.
