i wasnt using any mods
and what is happening is those wierd texts are showing. what should happen is those wierd texts dosen't show up but it shows.

do you have a solution to this?

so what am i supposed to do?

I've has this same issue. It happened to me with the crossbow animation so whenever a crossbow was used by another player, those messages would fill my screen and the animation wouldn't play. I assume that certain textures and codes get misinstalled which is causing the error messages. Sadly, the only fix I have found is to reinstall the game.  

@unknown: Does the issue still occur if you disable your resource pack?

@ocelotonesie it does appear without any recource pack applied. please find me a solution i would really appreciate any small tips

You can stop these error messages from appearing by going to Settings > Creator and disabling "Content Log GUI".

I'm closing this ticket as Incomplete because there's not enough information to reproduce the issue.
