When i join a realm that the owner plays on i get kicked and the owner does not, i have other friends who also play in the realm and they do not get kicked while the realm owner is online, but i do.  When i play alone in the realm i dont get kicked, i have tried everything that seemed safe and reasonable on the reddit post: https://www.reddit.com/r/Minecraft/comments/nvqicd/how_to_fix_internal_exception/

This is a bug for a lot of people if you read the reddit post you see that only there, it is over 150 people who has the bug. ( I have also tried restarting my pc, uninstalling and reinstalling java, Uptading java version( trying a lot of different versions) I even tried factory resetting my pc) Nothing have worked.
