Adding a sensor to the double slit experiment to measure which slit the particle goes through removes the quantum effects from the experiment.

  Not sure what you mean. Quantum effects don't "disappear". They are physical laws. Which slit the particle enters after the wave decoheres is precisely a non-deterministic element of quantum mechanics.

    But wouldn't measuring something also alter the outcome? Ie. Observer Effect https://en.m.wikipedia.org/wiki/Observer_effect_(physics) https://en.m.wikipedia.org/wiki/Observer_effect_(physics)

      It doesn't alter the outcome. It causes it to decohere into a particular outcome. There is no way to force a particular outcome, hence it being non-deterministic.
