I have Cubase 10.5.30, Windows 10, and I have been experiencing this problem since updating from 9.5 to 10.
I leave my session open and come back to it later. Sometimes Cubase will work when I get back to it, sometimes it doesn’t. It’s just stuck in some damn loop, using about 15 to 16% cpu according to Task Manager, and is nonresponsive. I have to restart the computer to free the audio driver.
Has this nonsense been fixed in 11, or is it still misbehaving?
