The measurement problem, quantum entanglement, the Bell inequality and consequent implications for non-locality or realism, are not phenomena you can dismiss as 'quantum woo' - or, as Einstein put it 'Spooky stuff at a distance'.
Strawman. I didn't say Bells theorem doesn't say either non-locality or realism are false? I didn't say entanglement isn't a mystery. What I remarked on is that consciousness affects the measurement. That specifically is what is considered quantum woo.
If you are genuinely interested, may I suggest you do some proper research rather than just googling something? Adam Becker, Michael Brooks, Carlo Rovelli and Sean Carroll are physicists who have written accessible books on the subject, as are philosophers with backgrounds in science such as Anthony Aguirre, Alyssa Nye and Jonathan Schaffer.
I have read plenty of pop-sci physics. Heinz Pagels, almost all of Paul Davies books, some of them several times (About Time) and around 20 individual authors like F. A. Wolf, João Magueijo, even Quantum Enigma by 2 Phds who explore the measurement problem.
It's weird that you are telling me to read poop-sci when I linked to physicsforums where in order to get certain credentials you have to show you are a professor with a degree?
That part of the measurement problem is considered woo. I see that pop-sci is big on selling these concepts. Unfortunately when I went to physics forums and tried to learn further information I found that it's not supported in physics. In other words, I did some further research.
But since it doesn't match what you believe to be true you assumed I just googled it? That would be cognative bias. Here is a thought, make a username and ask some physicists/advisors on the forum your question and see how it goes. The "advisors" have to show a degree and a teaching job.
The need for a "conscious observer"
"With the exception of the Wigner interpretation (for which even Wigner himself eventually withdrew support), a conscious observer plays absolutely no role in any of quantum mechanics. Collapse of the wave function (assuming an interpretation that posits it) is unrelated to consciousness, else the universe could never have evolved a conscious observer."

It's often explained by decoherance:
"It's been observed in experiments, so it's a fact. See, for example, this review article by Schlosshauer:
Quantum Decoherence"

The need for a "conscious observer"
"For all practical purposes, you can substitute a measuring device for a conscious observer. You can program a robot to write "The particle was measured to have spin-up" just like a human observer. The Rules of Quantum Mechanics would work just as well for the robot. Sure, you can take a skeptical stance and say that the robot doesn't actually know that the spin was up, you need a human to read what it wrote and interpret it. But you can apply the same skepticism to other humans---maybe only your observations collapse the wave function? Anyway, the Rules of Quantum Mechanics say, roughly, that: When a measurement is made, the result will be an eigenvalue of the operator corresponding to the observable being measured. Some people interpret the measurement to be made when a conscious observer learns the result. But if you instead, you interpret it as: the measurement is made when there is a persistent, irreversible record of the result, you get a variant of quantum mechanics that is experimentally indistinguishable from the first interpretation."

Does unitarity of the evolution of wavefunction get rid of the need for a "conscious observer", and does collapse in contrast demand a "conscious observer"?

are in principle answered. If all chain links in a von Neumann measurement chain are treated as pure physical systems – up to the end, one ends up - when basing oneself on the physical formalism of quantum theory and the Schrödinger dynamics in particular - with nothing but an entangled state. If the object of interest which is measured is, for example, represented by a superposition state a|+>+b|−>, the last chain link of von Neumann’s measurement chain ends also in a superposition state a|+,A+,E+,Me+>+b|−,A−,E−,Me−> where A+,E+,Me+ and A−,E−,Me− represent the state of the apparatus, the environment and the “observing” sytem at the end of the chain. That's the "physics"! There is - when all chain links are considered as pure physical systems - nothing which reduces the superposition of two possibilities to one unique actuality. As Euan J. Squires puts it (see reference in post #10): “So, where is the problem, and what has all this got to do with consciousness? The complete description of the “physics” in orthodox quantum theory is the state displayed above, which contains both terms, i.e. both “results”. The unique result of which I am aware does not exist in physics - but only in consciousness. The Born rule does not have anything to say about physics - it says something about consciousness.”

Conscious observers obey the same quantum theory as the rest of the universe. Conscious observers are irrelevant. Not to put too fine a point on it, but conscious observers are the ones who define "conscious," and aside from the inherent bias in that, there is no consensus to what that even means. Why would "conscious observers" be special aside from the desire of some conscious observers to think they are special and not subject to the same laws of physics that applies to the rest of the universe?

In fact I had to go to the "ask anything" section of the forum because questions related to nonsense are not allowed in the regular forums.
