ERROR_GRAPHICS_CANT_EVICT_PINNED_ALLOCATION

ERROR_GRAPHICS_CANT_EVICT_PINNED_ALLOCATION (0xC0262109) means the memory manager needed to evict an allocation but could not because the allocation was pinned. A pinned allocation must be unpinned or released before it can be moved out of the required segment.

What to check

Release locks, mappings, or explicit pins before requesting operations that require the allocation to be evicted.
Review the resource budget and avoid keeping large allocations permanently resident without a need.
If it follows a device reset, recreate resources rather than trying to preserve pre-reset pin state.
