[BUG] `qml.qsvt` breaks with some angles

[KetpuntoG]

Expected behavior

This code is not working

import pennylane as qml

a = 0.3
angles = [.1,.2,.3,.4,.5] 

print(qml.matrix(qml.qsvt(a, angles, wires = [0], convention = "Wx")))

Actual behavior

local variable global_phase referenced before assignment

Additional information

It breaks when the length of the angles is 4d + 1 for any d
