a wired thing in UI between editor and build!!!

i have an element in UI when i click on the button to show it.
it works perfectly on unity editor.
in build, it gives a not responding and stops the game.
what is that!!!

“Not responding” often indicates an infinite loop. Take a look at the player log for any errors, and I’d look at any loops involved in that button click.
