As the other person said, something is wrong if your machine is shutting down instead of just giving choppy playback.

Do you do much heavy CPU with with that machine at all? It’s possible that AV1 decoding is the only thing you’re trying to do that pushes the CPU to that degree. 7th Gen Intel CPUs have hardware decoders for h.265, so the CPU is barely used to play these back, but lacking a decoder for AV1 means it has to be decoded in software, which hits the CPU hard.
