Basis gate set with RXX gate converted with QASM3 and run with Aer simulator results in 'unknown instruction: rxx_139974866104288' #11560
Description
Environment
- Qiskit Terra version: 0.45.1
- Python version: 3.10.1
What is happening?
Creating a circuit that results in an RXX gate after being transpiled with a basis set of rx, ry, and rxx and then converting with QASM3 and running on an Aer simulator results in the following error:
Traceback (most recent call last):

AerError: 'unknown instruction: rxx_139974866104288'
Having the basis gate set, the QASM3 conversion, and the aer simulator are all required to reproduce the bug in this manner.
How can we reproduce the issue?
Run the following:
import qiskit
from qiskit import QuantumCircuit, ClassicalRegister, QuantumRegister
from qiskit.circuit.library.standard_gates import *
qr = QuantumRegister(2, name='qr')
cr = ClassicalRegister(2, name='cr')
qc = QuantumCircuit(qr, cr, name='qc')
qc.append(RXXGate(3.1067098743999053), qargs=[qr[0], qr[1]], cargs=[])
qc.measure(qr, cr)
from qiskit import transpile
qc = transpile(qc, basis_gates=['rx', 'ry', 'rxx'])
from qiskit import qasm3
qc = qasm3.loads(qasm3.dumps(qc))
from qiskit_aer import AerSimulator
simulator = AerSimulator()
counts = simulator.run(qc, shots=100).result().get_counts(qc)What should happen?
The circuit should be able to run without error.
Any suggestions?
