My Unreal Engine can start normally, but when I open any other Unreal Engine window, the two windows merge together like jelly (see image below), constantly flickering. Furthermore, if I close any window other than the main window, it crashes immediately (see crash report above).
However, apart from this, my Unreal Engine is otherwise functioning normally, and this only happens when I use DirectX 12; it doesn’t occur with DirectX 11, and this problem is consistent across all projects.
This crash may be caused by a null pointer dereference issue in the D3D12RHI module of UE5.7.1 when interacting with NVIDIA graphics card drivers. The problem occurs during the rendering pipeline initialization or execution, specifically when using the D3D12 rendering backend with NVIDIA graphics cards.
Please tell me how to deal with this stupid thing!!!
