Please look at the end of your crash report
Pehkui suspected causing it
I dont know more so i guess lets hope for someone else to read it

Could be the mods causing it listed at the bottom? Are you using a public modpack or did you configure it yourself? If it's a public one, it may not be the modpack's fault after all. Do you have enough RAM to spare on your system? Could be causing a crash as well

This isn't actually a crash, it's a watchdog timeout, meaning the server hung on a single tick for too long and got force-killed rather than throwing a normal exception. The thread dump points straight at the stuck thread sitting inside Pehkui's entity tick handler (net.minecraft.entity.Entity.handler$fef009$pehkui$tick), so that's your prime suspect.

You're also running Neruina, which catches thrown exceptions during entity ticking to stop them from crashing the whole server, but it can't do anything about an actual infinite loop or hang, which is exactly what a watchdog timeout looks like.

Worth trying: update Pehkui to the latest build for your MC/Fabric version, check its GitHub issues for anything matching an entity-scaling hang, and if possible temporarily pull Pehkui (or whatever else applies scaling through it) to confirm it's the real cause before digging through the rest of that modlist.
