Desktop computer freeze which blocks all the local network‽ (sh.itjust.works)

I have assembled my desktop PC about 2 years ago. It's fairly beefy (AMD Ryzen 9 3950X 16-Core Processor, 128Go RAM, nVidia RTX 3080 Ti). It's running debian stable.

Once in a while (not that often, but like every 2 weeks or so), seemingly at random times, not especially under heavy loads, the system crash and freeze, irresponsive to even the linux sysrq magic keys. I never manage to find what was the cause. One interesting fact is that when it happens, for some reason it seems to "freeze my network" too, ie, other (ethernet) devices on my local network have no connectivity anymore. They're all connected to the same router, but not through this crashing PC. Connectivity comes back as soon as I force shutdown the crashing PC.

What can cause this and how could I fix these freezes?

Is it possible that the freeze you're seeing on that machine is actually caused by a network failure, rather than the other way around?

I have encountered many times what appears to be a system freeze which is actually the result of background processes trying to access a network resource which no longer exists(eg, mounted a disk via VPN connection, but the VPN has dropped out)

I think this is unlikely because it's only this specific device that crashes, and the others are fine?
