The build crashed natively (UnityPlayer, no managed frames) during the
match-end paint carry, where LoadPaintFromSnapshot/ReseedCanonical tears
down and rebuilds all RenderTextures with DrawMeshNow/Blit and ReadPixels
from LateUpdate, on multiple painters at once. D3D12 is far stricter than
D3D11 about this immediate-mode + RT-lifetime churn outside the render
loop. Pin the Windows standalone graphics API to D3D11 (D3D12 fallback)
as a mitigation without touching the paint architecture.
