I have a strange issue with the latest 12.0.20 . for some reason Cubase app wont completely shutdown. There is an instance left stuck in Task Manager under the Background processes and the only way to stop it is to use the End task option in Task Manager. This happens on windows 11.
What i noticed also that this issue is more prominent after using Mixdown and also when quitting via the File/quit menu. If I quit by closing it via the x window button (top right) quits normally.
