Program just quits responding?

I haven’t used it on my pc in a few months. I updated it through the IK product manager. Sometimes I can play for a hour or two no issue. But some times the program just locks down, no audio comes through. The sound levels stay frozen in eq. And I have to force quit the program. Kind of a drag tbh, does anyone know a solution for this? Or am I the only one with this issue? Thanks for any input, rock on
