Just in case you’ve not seen the latest developments on the other thread here: https://www.eventideaudio.com/forums/topic/h90-control-app-no-longer-seeing-h90/
If you’re using either Avast or AVG antivirus software, their latest updates stop the H90 control app from seeing the H90 (I tested both applications under Windows 10 today).
I’ve switched to Avira and H90 Control is now working normally again.
