Hello @tsctsc66 , Welcome to the forum!
From the error message i can see it’s related to GPU and DirectX 12. Here are some possible solutions:
- Have you tried updating your GPU Drivers to the latest?
- Since the crash involves D3D12RHI it could be an issue with DirectX 12 rendering, try switching to DirectX 11.
- It could also be an overheating issue with your GPU, check your temperatures.
- Unreal could be running out of VRAM causing the GPU to crash.
Try these out and let me know if it helps.
