Hello, So im hosting a Minecraft 1.21 server with spigot to add a few plugins but when i finally went to the end i jumped in the portal and ther server just insta crashes so i reset the end and tryed again still crashed. so i thought it was something else so i used this cmd
[

1. /execute in minecraft:the_end run tp @p 0 100 0

]

To enter the end but still crashed after while thajn i disabled all the plugins and tryed again still crashed but when i switched over to just the normal 1.21 update i went in the end fine.

now idk if its my dumb self or something else i just thought if it is a bug with spigot i would like to let you guys know but again im not really sure what the problem was Thank you!

Here is some of the crash report
