When opening saved project it's playing veeery slowly

hi guys, I’ve been working on a new project for the past couple days and now I have the problem that when I open the saved project it’s playing the tracks very slowly. I set a 100 bpm but even if I change it, the tempo won’t change at all. Don’t know what to do, any help much appreciated…!

Hi and welcome,

Make sure the Sample Rate of your project matches your Audio Device Sample Rate.
