Please describe your issue as accurately as possible:
Lords of the Fallen (2023) crashes approximately 10 seconds after launch with a LowLevelFatalError in D3D12RHI. The game shows a black screen, hangs briefly, then crashes. EasyAntiCheat initializes successfully and is not the cause. The Proton log also shows warn: D3D11DXGIDevice::QueryInterface: Unknown interface query preceding the crash.
Exact error from CrashContext.runtime-xml:
