Hm, yeah, maybe not that then. In that case I have no idea, I just know I've used VSCode on a lot more resource-constrained machines than that and can't remember ever having it cause a whole system crash.
(Actually, not completely true -- once I set up a NixOS machine with 8GB of RAM and forgot to make any swap for it for some stupid reason, and that one definitely got completely hosed if I tried to open up e.g. Codium and Firefox at the same time. But not for any machine that was set up right 🙂.)
