loop "While" stopped at the click of a button

how to make the loop "While" stopped at the click of a button "btnMove"?

see here why using a while loop is probably not a good idea

The model of event processing in App Inventor by Lyn

you might want to elaborate, what you are trying to do

this could help us to suggest a solution...

Probably the button click is never recognised because the wile loop never finishes and it does not allow being interrupted.

Pull a Clock in from the Designer's Sensors drawer.

Move the blocks from your while() loop into the Clock's Timer event block to have them repeat.
