CPU stuttering when engine Multithreading active

I haven't been able to play normally for a while now because of these crashes, the screen freezes every 3 seconds. I have to restart the game several times, switching between Vulkan and DX12 until it stops.

At first I thought it was a temperature problem and I even bought a new expensive cooler, but the problem persists.

Note: If there is no effective configuration for a long time, the problem soon starts again.
