UE 5.5 DX12 Virtual Heightfield Mesh Crash.

As the title says - Virtual Heightfield Mesh Crashes in ue 5.5 with dx12. And dx12 is required for lumen. Is there any plan on fixing it, supporting it in the future? I would really rather not use nanite for this, because the performance is so much worse, atleast in my use case where I have a very low poly world, but still need some higher detail on landscape for snow, etc effects.
