Every solution in the forum tried but Media Texture/Video only playing in editor not in package

Hi everyone,

i have several videos in my level and every one of them plays in the package except one.
I tried other formats, pathchanges, OnMediaOpend, EventTick, etc…mainly every solution posted in this forum but not one of them works for me.
Does anyone have an (other) idea how to fix this? That’s the (simple) blueprint that i have for every video.
