It has been supported by none other than the pioneers of QM and the idea that Mind or Consciousness is fundemental is accepted by many prominent Physicists. The Observer effect (conscious choice) in QM is supported as one of the possible interpretations of QM and is widely supported with experiements like the Double Split, Wigners Friend and the Delayed Choice experiment.
It was also supported by Chalmers in the video when he said Panpsychism can be a possibility. They spoke about the impossible gap between Matter and Consciousness that cannot be explained by reductionist material explanations. So its not out of the possibility. What they were more or less saying was that we have given names and descriptions of phenomena at the sub atomic level but we don't know what we are explaining actually is, what its nature is.
Explaining or describing how something is does not account for its nature. Doesn't make it a physical thing. At the fundemental level nothing is actually physical, there is no Mass or Matter. So all cards are on the table. What we may be describing at the fundemental level could well be associated with Consciousness we just don't know. So to say that consciousness or Mind is just Woo and therefore discount it as a possibility is Woo itself.
Add to this that there is a growing body of Journals, scientists and ideas including those mentioned by Chalmers like Panpsychism, QBism, the Quantum mind, Integrated Information, the Global Workspace, Intentional Schema theories and the many variations I would say calling the possibility of fundemental reality being some form of Mind or Consciousness Woo is way premature.
Many scientists have come to the Copenhagen Interpretation as their conclusion for understanding reality. The Copenhagen Interpretation comes from the school of quantum mechanics, and it believes that reality does not exist without an observer to observe it.
Pioneering physicist Sir James Jeans wrote: “The stream of knowledge is heading toward a non-mechanical reality; the universe begins to look more like a great thought than like a great machine".
Theoretical physicist and mathematician
Freeman Dyson says: "mind is already inherent in every electron, and the processes of human consciousness differ only in degree but not in kind from the processes of choice between quantum states we call “chance” when made by electrons".
Pioneering Quantum physicist David Bohm: "
We have something that is mind-like already with the electron'.
Henry Stapp one of the greatest physicists on QM who also worked with Quantum pioneers Wolfgang Pauli,
Werner Heisenberg and J.A. Wheeler who also support Mind and Consciousness as fundemental and has made many arguements in scientific journals on Mind being fundemental.
Stapp: The acquisition of knowledge does not simply reveal what is physically fixed and settled; it is part of the process that creates the reality that we know.

Then you have John Wheeler Participatory Universe principle
John Wheeler’s Participatory Universe
Image: The New York Times John Archibald Wheeler (1911-2008) was a scientist-philosopher who introduced the concept of wormholes and coined the term “black hole”. He pioneered the theory of nuclear fission with Niels Bohr and introduced the S-matrix (the scattering matrix used in quantum...

And other ideas being argued and having a scientific basis.
The “new wave” of panpsychism lacks the mystical connotations of previous forms of the view. There is only matter – nothing spiritual or supernatural – but matter can be described from two perspectives. Physical science describes matter “from the outside”, in terms of its behaviour, but matter “from the inside” is constituted of forms of consciousness. This means that mind is matter, and that even elementary particles exhibit incredibly basic forms of consciousness. What panpsychism offers us is a simple, elegant way of integrating consciousness into our scientific worldview.

Quantum Theory Demonstrated: Observation Affects Reality
A quantum object cannot be said to manifest in ordinary space-time reality until we observe it as a particle. The quantum object exists indefinitely as a non-local wave until it is being observed directly. Consciousness literally collapses the wave-function of a particle. without a conscious observer present to collapse this wave, it would remain physically un-manifested in a state of potentiality . Observation not only disturbs what has to be measured, it produces the effect.
