Black screen after a tot of working on my project.

Hello, and since I put the Niagara in the 3D scene that my screen started to lose the signal every time… I tried to remove that niagara from the scene thinking that was the problem but still lost the signal after many minutes but I get back to work it was 30 minutes and then the monitor loses the signal.

I’m desperate! I did from the 2 Windows keys “Tdr…” and updating and reinstalling the Nvidia drivers of my RTX 3070. I also used the MSI afterburner with Core at -200 but it doesn’t even work that way and I tried to start UEFN with -dx11 but don’t work it.

I also play well and have never had any problems with other games but it is only UEFN that causes my Monitor to crash into Black and I have to forcibly turn off my PC from the center button.

Someone help me with my case, and if that works, I promise to insert an eastregg of that person who will help me solve the problem.
