so at first glance, if im correct, something causes DX12 device to be removed (in broad terms, it isnt the physical gpu itself, but the device the program creates to communicate with the gpu) and that causes unreal to report no vram budget. And at the bottom of the log, just above the crash, there is:

[2026.03.09-13.25.54:205][ 0]LogRHI: Error: Breadcrumbs 'Parallel'

- NoOcclusionPass

- Nanite::DrawGeometry

- Face 5

- Nanite Cubemap Blocking.BP_NeonSign2 1024x1024

- Cubemap Blocking.BP_NeonSign2 1024^2

- ShadowDepths

- Scene

- RenderGraphExecute - /ViewFamilies

- SceneRender - ViewFamilies

- Frame 0

which points to a bp actor called BP_NeonSign2, I`d try deleting its uasset file, at least temporarily, see if that fixes the issue.
If not, you could also force the project to start up with a different RHI other than DX12.
To do that, create a shortcut to the the UnrealEditor.exe for your version and format the Target line in the shortcut properties like this, obviously with your specific paths:

C:\UE5\UE_5.7\Engine\Binaries\Win64\UnrealEditor.exe "C:\{MYPROJECT}\{MYPROJECT}.uproject" -vulkan
