Cubase 11 issue, audio messed up and doens't match what was recorded on all my projects

is this a common issue??? I was working on a project, and the next day, my project meesed up, all the instruments and plugins loaded correctly but when I push the play button, nothing matched with what I have done or what is recorded or written in Midi, not even the tempo… now all my projects are like this and I can’t find any solution.
did anyone know how to solve this ???

Did you change sample rates? Never heard of such a weird thing happening.

I have already treid that with no luck

Ctrl-p. Then uncheck “musical”
