The GPU-AV enable list was removed to dodge a crash in SDK 1.4.341,
whose GPU-AV null-deref'd on descriptor_heap pipelines
(VK_PIPELINE_CREATE_2_DESCRIPTOR_HEAP_BIT_EXT, layout = VK_NULL_HANDLE)
in PipelineSubState::GetPipelineLayoutUnion:
https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/12103
That was fixed in the next SDK release. The validation layer is now
1.4.350 (> 1.4.341), so restore VK_VALIDATION_FEATURE_ENABLE_GPU_ASSISTED_EXT
in the VkValidationFeaturesEXT enable list.
Verified by running the HelloUI example (which draws through the
descriptor_heap compute pipelines) with the layer active: it renders the
full UI for the entire run with GPU-AV reporting "Both GPU Assisted
Validation and Normal Core Check Validation are enabled" and no
descriptor-heap null-deref or VUID errors.
