Additional update: I tested 26.1.2 and the same issue still occurs.
The game again crashed with EXCEPTION_ACCESS_VIOLATION (0xC0000005), with the same problematic frame, igxehpgicd64.dll+0x84ab4f. The attached crash report shows that the crash occurred on the Render thread during startup.
So this issue is also present in 26.1.2.
After removing the OpenCL / OpenGL / Vulkan compatibility pack in 26.2 Snapshot 1 and testing again, the VK_KHR_push_descriptor error disappears. However, the game still crashes without generating an hs_err file.
