Description
Hitting this VU now:
Fossilize ERROR: [Layer]: Error: Validation: Validation Error: [ VUID-VkDeviceCreateInfo-None-08095 ] Object 0: VK_NULL_HANDLE, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0xe6a1c10a | vkCreateDevice(): If the descriptorBuffer feature is enabled, ppEnabledExtensionNames must not contain VK_AMD_shader_fragment_mask. The Vulkan spec states: If descriptorBuffer is enabled, ppEnabledExtensionNames must not contain VK_AMD_shader_fragment_mask (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-VkDeviceCreateInfo-None-08095)

Research direction
No file, test, or entry point is named. Locate the replayer's device-extension selection and inspect how descriptorBuffer and VK_AMD_shader_fragment_mask are handled; done means the invalid extension combination no longer reaches vkCreateDevice and the reported validation error is no longer reproduced.
