Screen hanging while syncing vcv beatstep pro

Hi alltogether, Maybe the problem is known, but found no solution! At the moment, when I try to sync keystep pro to vcv, vcv starts to hang every ~20 sec. For about 2-3sec. It seems to be only the screen is hanging, sound runs well? Has somone an idea? I’m working with macOS (latest) on a macbook pro. Best regardes
