I don’t understand how measuring something, or detecting something, CHANGES that object’s circumstances. It’s like saying that a tree isn’t 50’ high until I take a tape measure and measure it, but how can that be right, a tree has physical properties regardless of whether I take a tape measure and measure it...

I know. It’s a difficult concept.
But it’s kind of like my sunglasses example. The view (of the universe) does NOT exist until I chose a pair of sunglasses. And I have no way of picking one pair of sunglasses instead of the other.
QM exists in a kind of world where there are many dimensions. Actually, an infinite number of dimensions. But not just dimensions like we are used to like time and space. Other dimensions, like mass and charge and velocity and position and more and more and more dimensions.
I think it was Bohr who said something like “If you think you understand QM, you obviously don’t, because NOBODY does or even can.”
A good book about it is “Quantum Mechanics and Experience” by David Z Albert of Columbia University.
