CircuitError: 'Name conflict on adding parameter: Φ'

[MatP1337]

While trying to construct a circuit with:

  from qrisp import *
  from sympy import symbols

  phi = symbols('Φ')
  beta = symbols('β')

  test=QuantumVariable(4)
  with control(test[2]):
      xxyy(phi=phi,beta=beta,qubits_0=test[0],qubits_1=test[1])

  with control(test[3]):
      rx(phi=phi,qubits=test[1])
  print(test.qs)
  compiled_qc = test.qs.to_latex()
  print(compiled_qc)

It returns a CircuitError: 'Name conflict on adding parameter: Φ'
