Audio tracks going silent, midi tracks not playing

I have been getting into using Cubase. And the more familiar I am getting with it, the more the bugs start bothering and baffling me. Tracks I record will suddenly go quiet for no reason that I can discern and can’t be switched on anymore, it seems. Midi tracks will stop playing their VST instruments, for unknown reasons. And after some research online, I am learning that this is something many people experience. This makes this program a chore to work with.
Could you please fix these bugs and perhaps offer a work-around to deal with the problem, until then? Thanks in advance.

I know a few people including myself using Cubase 12 and we never see this. Have you got an example plus all you system details, screen shots of what you are doing. All sorts of user errors can cause this.
