every time i enter my server it closes

my friends can enter the server normally, but when i try to enter it closes after seconds, sometimes the server lasts a little longer but never stays open with me online, i wasn't having this problem before, it started out of nowhere

here's my log file

i found it, my server has an addon and an especific item is making it crash, i guess its because minecraft 1.20 is having issue with items adding effects, thanks for checking out my thread even if it doesn't have a solution yet
