bug where when im on the bedwars map in hypixel it closes the game and puts exit code -1

im sorry for saying its version 1.21.1, it doesnt let you say 1.18

Basically, everytime im in the bedwars map, my game goes out and says a message. I've tried everything, from reinstalling the game, to checking if my computer was up to date but it always said 2 things, either

elgh(g) is null (basically what it says)
or
java(lang) (not what it says)

oh yeah, this only happens in hypixel and my graphics are to the minimum it can be

watch it for yourself to see what i mean
