Kind of feels like in my opinion, yeah, I’d be looking at site-side first too, annoying as that is. If GSC’s mostly flat and it’s just certain pages that stalled, that’s usually not some big scary update. I’ve had this happen a bunch of times where it turned out to be dumb stuff like internal links getting changed, a template tweak, or a canonical going sideways for no obvious reason. That said, Google’s been weird enough lately that I wouldn’t totally rule it out either. But “traffic tanked” and “a bunch of pages stopped moving” are two different animals. If impressions are still there but clicks dropped, that’s one thing. If impressions actually fell off, then yeah, something changed. Den’s probably right on the boring stuff first, even if it’s not the sexy answer. Sadly that’s usually where the mess is.
