Project Tempo and Transpose is changed automatically ERROR

I opened a project in Cubase and noticed that the tempo and transpose is out of control, transpose is about 1-2 levels up and tempo is too fast.
So what should I do or how to resolve this error??

Thanks!

Hi and welcome,

Most probably the Project Sample Rate and your Audio Device Sample Rate doesn’t match. Change it in the Project Setup (Shift + S), please.
