Cubase 13 started playing back sharp?

Been doing a song on Cubase 13, shut everything down as I needed to pop out. On bootup my project is playing back nearly a tone sharp???, loaded up some earlier projects and they are also. |My sample rate has not changed and bit rate is the same.

Hi,

Make sure the Project Smoke Rate matches the Audio Device Sample Rate, please. Mostly this happens, if one of them is 44.1kHz and the other one is 48kHz.
