If it is not the temperatures and it is not a outdated driver, then it is caused by the game itself + some other app running together. See if you eliminate that companion app and if it continues to crash.
I was probably playing Beat Saber at that time. For some reason Beat Saber seems to overload my system more than an actually good looking VR game.I don't know what game you were playing here but whatever it was it was really loading your system.

I'm pretty sure there's only 2 fans for the entire laptop. I'm not entirely sure, but when I opened it up I only saw two.How many front fans do you have (blowing IN fresh air) ? How many back fans do you have (sucking out hot air)? Good cooling is important especially when you cpu reaches above 90 C.
If adding more fans do not help, then you may need a better cpu heatsink.
