They are being extremely random and utterly stupid with layoffs, all of the larger developers.
I've seen the best technical artist being fired right in the middle of transition from built-in rendering pipeline to URP, which is THE thing where you need a technical artist that understands your shaders, especially if the game has a lot of custom ones. There wasn't even a reason for it, just general layoffs. I've seen people who have been in the middle of working on larger features that are important part of the game being fired, without any warning and cut access after the weekend, so there's no time or chance for handover.
It sucks, even AI could do a lot better job with this, i.e maybe not firing the devs that thave the most important knowledge.
