If PcdDxeNxMemoryProtectionPolicy is set to enable protection for memory of EfiReservedMemoryType, the BIOS will hang at a page fault exception triggered by BootScriptExecutorDxe. The root cause is that this driver will allocate memory of EfiReservedMemoryType and relocate itself into this new memory. Since EfiReservedMemoryType of memory is marked non-executable, re-start this driver after relocation will cause exception. The fix is removing the NX attribute after memory allocation.
