Transpiler optimization_method="zxpass" gives wrong result

[BankNatchapol]

Environment

• Qiskit version: 1.1.0
• Python version: 3.10.12
• Operating system: Google Colab

What is happening?

Circuits after Transpilation should give similar result, but not.

How can we reproduce the issue?

from qiskit.quantum_info import Statevector
from qiskit.compiler import transpile

with open('acircuit.qpy', 'rb') as handle:
    qc = qpy.load(handle)
wo = transpile(qc, basis_gates=['cz', 'swap', 'cx', 'tdg', 's', 'sdg', 'h', 'rz'], optimization_level=1)[0]
w = transpile(wo, basis_gates=['cz', 'swap', 'cx', 'tdg', 's', 'sdg', 'h', 'rz'], optimization_method="zxpass")

print(Statevector(wo))
print(Statevector(w))

ill attach acircuit.qpy acircuit.zip

What should happen?

the statevector should be the same.

Any suggestions?

If it's correct, please guide me how to make the statevector output to be the same. Thank you in advance.

We don't define an optimization_method called zxpass; you must be pulling that in from some external plugin.
