you do not specify engine version in 3.x, no perspective lens is the only accurate one for this class.
in alpha 4.0 we've just updated the unproject code, and it should work. but because its not tested with this class the class checks and assign a lens by default if not Perpectivelens you could comment the init method content to try and see if it works.
