Should I just submit to the fact that Unreal Engine 5 will cause my computer to crash?

I’ve experienced the same issue on four different computers at a PC

What CPUs - specifically?

Is this a common issue, or could there be something specific I’m missing?

Not common; it could be the Intel microcode shenanigans that have been crashing systems on the higher-end of the CPU spectrum. The august BIOS updates should now be available for most motherboards, though. A must have unless the overvoltage has already damaged the processor, that is.
