We read the address map before assigning the memory for the pages that will be mapped to virtual addresses. So these pages will overlap with the entry for EFI_CONVENTIONAL_MEMORY. We have to ensure that every page is described at most once in the map.
Remove EFI_CONVENTIONAL_MEMORY from the map that we pass to SetVirtualAddressMap().
