You are trying to hash a hex string not binary data.
Working example:
import pyrx
import binascii
import struct
def pack_nonce(blob, nonce):
b = binascii.unhexlify(blob)
bin = struct.pack('39B', *bytearray(b[:39]))
bin += struct.pack('I', nonce)
bin += struct.pack('{}B'.format(len(b)-43), *bytearray(b[43:]))
return bin
seed = binascii....
