Game crashes whole PC when multithreading enabled

Hi,

My game crashes since launch of early access and it freezes the whole PC, so I have to force power off and power back on the whole PC again.

I have noticed this only happens if I have multithreading enabled. Obviously with it disabled, the performance in big mob packs is awful.

Here are my specs:
7800x3d AMD CPU
RTX 3080 nvidia GPU
2x16GB DDR5 G.Skill RAM running at 6000mhz
Asus AM5 B650 motherboard
Corsair SF850 PSU

GGG, what is the next step here please?
