Strange. My work laptop is a 2019 13" pro with only an i5 and 16GB RAM, and I very rarely have any problems. On the rare times I do, it's usually because some app went nuts and needs to be killed. Google Hangouts, however, is a pig.
But then, when on a Hangouts (now Meet, I guess) call, I typically won't be pushing any of the other apps; they'll be idling.
