Record format changed?

I recently opened my cubase elements 9.5 and record format has changed?
all my projects are now playing slow and out of sync
97kHz 16bit is highlighted in orange, I put it to 44kHz 16 and it went blue but still out of sync.
Can anyone help me out with this,
Thanks

Hi,

What is your Audio Device Sample Rate, please?

Out of sync with what, please? What is the other source?
