Bug in Cubase 10 + 9.5. Stuck tracks, non editable

After recording either midi or audio, my tracks get stuck and I cannot move them. I cannot record over the track, I cannot delete tracks, when this happens also undo and redo function stops working as well. I have deleted prefs as well as reinstalled cubase on my imac that is running high sierra. Still keeps occuring.

Hi and welcome,

Make sure the tracks are not Locked, or the recorded events are not Locked.
