ASIO-Guard-what is wrong with C12 !?!?!?!?!?!

This is just starting to get unbearable !!!
First, peaks and real time and disk cache didn’t let me record anything.
Now, after opening a blank project - my ASIO-Guard - all the way to the write and cracking !!!
All of this after I installed C12.
Steinberg - why can’t this be fixed?!? What did you do?
And now C11 works the same f/up way!

Windows or Mac? Win updates can cause problems. Cubase 11 should not be any different so it sounds like something else
