Ciphering services not available error on pysnmp v3 walk

I can run this command from the command line:

snmpwalk -v3 -m +MY-MIB-ROOT -m +MY-MIB -l authPriv -u MYUSER -a SHA -A "XXXXXXXX"  -x AES -X "XXXXXXXX" 1.2.3.4 .1.3.6.1.4.1.52330.6.1.2

I am trying to implement the same command in a python script using pysnmp:

import asyncio
from pysnmp.hlapi.v3arch.asyncio import *
from pysnmp.smi import builder, view, compiler
import logging
logging.basicConfig(level=logging.DEBUG)

# snmpwalk -v3 -m +MY-MIB-ROOT -m +MY-MIB -l authPriv -u MYUSER -a SHA -A "XXXXXXXX"  -x AES -X "XXXXXXXX" 1.2.3.4 .1.3.6.1.4.1.52330.6.1.2


# Load MIBs
mibBuilder = builder.MibBuilder()
compiler.addMibCompiler(mibBuilder, sources=['file:///usr/share/snmp/mibs'])
mibViewController = view.MibViewController(mibBuilder)

loadedModules = mibBuilder.mibSymbols.keys()
print("loadedModules:", loadedModules)

async def run(varBinds):
    snmpEngine = SnmpEngine()
    while True:
        print("A")
        errorIndication, errorStatus, errorIndex, varBindTable = await bulkCmd(
            snmpEngine,
            UsmUserData(
                'MYUSER',
                'XXXXXXXX',
                'XXXXXXXX',
                authProtocol=usmHMACSHAAuthProtocol,
                privProtocol=usmAesCfb128Protocol,
            ),
            await UdpTransportTarget.create(('1.2.3.4', 161)),
            ContextData(),
            0,
            50,
            *varBinds
        )
        if errorIndication:
            print(errorIndication)
            break
        elif errorStatus:
            print(
                f"{errorStatus.prettyPrint()} at {varBinds[int(errorIndex) - 1][0] if errorIndex else '?'}"
            )
        else:
            for varBind in varBindTable:
                oid = varBind.__getitem__(0)
                print(oid)
        varBinds = varBindTable
        if isEndOfMib(varBinds):
            break
    return

asyncio.run(
    run([ObjectType(ObjectIdentity('1.3.6.1.4.1.52330.6.1.2'))])
)

I get this error:

Ciphering services not available

I am running the script within a virtual environment on Red Hat Enterprise Linux release 9.4 (Plow)

$ pip list

If anyone else comes across this issue, the latest release makes use of the cryptography package so it worked after I installed that:

pip install cryptography

This was version 43.0.1 at time of writing.

pycryptodomex can be removed
