Unreal engine 5.6 new version compiled build animations glitches

I have been working with the latest Unreal engine versions, but when I create the build with the new version, the characters animations gives notorious glitches, not in engine just on the build, something curious is that when I change the graphic settings in mobile, independently of with setting I change, it fixes, just for the visible characters.

Is this happening to anyone?, is this a result of some skeletal mesh optimizations of the new version?, maybe is because the new retargeting system?, I didn’t do any retargeting of the animations in this version but I did that on other versions and those animations passed to the new version as well as all the assets of the project.
