Logic Pro Timing and Key Issue

Does anyone have a quick solution to this issue? 

I was tracking some vocals during a session before Logic randomly starts playing everything out of time and out of key. 

The vocals are way lower and everything is out of time despite being in time on the grid. 

I've tried all of the usual first steps (closing it, restarting and re-opening etc.) but no luck. 

Quick video for reference, an early version of the session vs the cursed project.

Thanks in advance for any help!
