when i enter the end , for the first time in my device , everything goes alright but something was a little bit off when i got to the coords 0 , 0 the unfilled ender portal was not there
i started searching for it until i found it
it was in the sky and below the dragon egg coords the bedrock which was there was replaced with a single unbreakable barrier block
command blocks and behaviour packs were not enabled (except the kill aura pack)
so , how do i fix this?

the thing that should happen is that the unfilled / filled (both portals) should be on the y = 50 and up (i don't know I am dumb) but as i remember the dragon egg place is always on the coords 0 , 64 , 0

and , if you need the addon for more information, (kill aura) here it is!
