Development Programming & Scripting Blueprint

I saw a thread (UE-81742) that seemed to have fixed what I’m going through right now - and I get the exact same crash error with line 249 in the D3D11RHI

Any ways for me to prevent this from happening?

I had same issue and I think this is happened to me because of a new Windows Update. I always get D3D11RHI error even if I move a blueprint node. Just random crashes.
I set DefaultRHI to DirectX12 and Vulkan, the crashes are not that much anymore.You can try that but just in case don’t forget to save your work every 5 minutes.
