Measurement can change what is measured, but it doesnt change it from illusion to reality.
I cannot measure santa clause into existence. But I can change the temperature of some water by measuring it with a very hot thermometer.
That measurement changes what is measured is the norm in almost all cases, except in classical physics which describes highly simplified highly controlled experiments. The only 'unusual' thing about QM is its a case in physics where measurement necessarily changes the system, but this is extremely common in every other area. It is more unusual that in classical physics, measurement doesn't change the system.
