Cubase stopped working completely

in the middle of the project sound stopped working, I ctrl alt delte and ended desk )like i always close cubase) I restarted th ecomputer and cubase doesnt start or open anymore. restarted again still not working.

Well the rest of us don’t know what Cubase, what o/s or what exactly is happening when you try to start it so at the moment you’re the only one with the info likely to help diagnose the issue.

inserted dongle into different usb port, now cubase is working again.
even thou dongle was always in that same port for years, and now it stopped working on that particler port. strange strange strange
