Microsoft added Tiled Resources Tier 4 to D3D12 in KB5065789 and the game only accounts for 1 through 3, in a 4 case switch statement with the default being disabled / not supported. The system returning Tier 4 causes the switch to fall over itself and return not supported.

Retract or update please, Nvidia did not break the game, the game was always broken and would always eventually hit this when the OS added new d3d12 features.
