Some substrates of n channel transistors are connected not to ground, do you use dip nwell?
You need to run a DC analysis, apply 0.5*vdd to inputs of OP AMP, and see states of all transistors and node voltages.

It looks like current mirrors transistors are in linear mode. Or gm of input diff pairs has very low value.
