My client crashes when I get into my server!

Hello.

I have a 1.19 PaperMC Lifesteal server, but when I log on or 5 minutes later from my login, my client (Lunar) crashes. I'm joining Hypixel, etc. but it doesn't happen there.

Oh, my friend joins too but that doesn't happen to him (also he is using Minecraft Launcher, not Lunar).

Please help me.

Thanks;
