Cubase 10.5.12 CPU Goes Crazy

Well, just reinstalled MAC OS Catalina, then installed fresh copy of Cubase Pro 10.5.12 and my project start stuttering and stopping and freezing, not being able even to stop the playback. Please fix that. There are numerous complaints about 10.5.20 with the same issue, but the problem is here on 10.5.12 too. CPU usage goes all the way to the 100%, it’s like I am playing some heavy PC game…

The glitching stopped, as soon as I chose the 64 bit float in VST Audio System.

Update: STILL CPU Overload…

The only solution seems to be ASIO GUARD to High… Otherwise it’s stuttering and the DAW is completely unusable. Yesterday, when I first posted the problem, I was with newly installed Catalina, since no one answered, and I am on a clock, I brought my MAC back to newly Sierra, same thing. Please fix Cubase for MAC. I also have it on Windows, no issues there…
