Consciousness-Collapse Is Wigner, Not Bohr

The Copenhagen interpretation does not actually attribute wave-function collapse to consciousness; that view was proposed much later by Eugene Wigner and is believed by almost no one. Bohr and Heisenberg tied collapse to measurement and a microscopic/macroscopic distinction, explicitly denying any role for consciousness—and von Neumann's formalism is what forced the wave function to evolve in two incompatible ways.
