Necrotic Wake Comet Storm Freezes Entire Computer

Nalthor the Rimebinder’s ability “Comet Storm” consistently freezes my laptop in normal mode. This never used to happen up until the past few days. Doesn’t seem to be an issue in mythic+, although I haven’t ran a NW key in quite a long time, so I can’t be 100% sure. 2019 Macbook Pro 16-inch with Radeon Pro 5500M GPU.
