Visibility glitches and artifacts (only on executable game)

Hello. I have a problem with visibility glitches and artifacts.
Everything else works fine, also it shows up only on executable version. There are no problems when playing the game from editor.

I have a character, combined of several skeletal meshes components. She’s animating on animation blueprint.
It doesn’t matter how close or far from camera.
The problem is not visible when I switch to low settings (lowest).

Do you know any solutions?
