Does the blue force disappear?

In my animation
there is a horizontal balance on whose point C a blue vertical
gravitational force acts (mg=10).

Pressing "Start" the balance tilts from zero to 90 degrees and the blue
force breaks down into the green force (perpendicular to the balance)
and the red force (which has the same direction as the balance).

The red force increases from zero to 10, the green force decreases from
10 to zero, and the blue force remains unchanged.

If someone told you that when you go from zero to 90 degrees, the blue
force disappears, would you believe them?

Evidently the discussion is not passionate.

I ask the last question and if there are no answers, the discussion
will be definitively closed for me.

Is it true or not that the condition with the balance horizontally
corresponds to the elevator stopped at the floor and the balance with
the angle of 90 degrees corresponds to Einstein's elevator in free
