My loading bar animation freezes up during loading

first off, don't know if this is the right place to post this or even if this is the right way to make a post I'm very new to posting on these forums. but I am having an issue where I have a simple animation on my loading bar that is supposed to play during scene load but it freezes up including the whole loading bar meaning the bar goes from 0% instantly to 100% with the animation being completely skipped, is there any way to help my loading bar to become smoother?
