Problem with pitch after saving project

Hello, I have problem with most of my projects, not all.
So when I partly finish my project and save it as cpr file, next time i get into that project pitch of one track or few tracks is transposed somewere between +1 and +2, probably 1.5+. Sometimes my whole project transposes not just few tracks. I would like to now why is this hapening and how to solve that problem. I am using Cubase 12 Pro, and Windows 11 Pro.

Hi and welcome to the forum,

This happens if the Project‘s Sample Rate doesn’t match the Audio Device’s Sample Rate. Please, set the same.
