Cubase 11.30 disk cache overloads

New issue on a MacPro 3.33 6 core/Cubase Pro 11.30. Really out of the blue Disc cache overloads when navigating forwards or backwards with a stutter when put into play. Lots of reports of this on the net with no solution. Have tried all of the usual suspects/changing drives, reinstall, buffer size, turning all the Studio parameters on and off to see if it makes a difference etc. It will happen with just one audio file in the session and nothing else. Very strange, anyone else had this and fixed it.

no idea how to fix it but got the same problem, except that I use Pro 11.3.0 on Windows…
