My skyfactory 4 server keeps crashing after 40 to 50 minutes or so

My server, Skyfactory 4, keeps crashing after 40 to 50 minutes. Any ideas on how to fix this?

I play with my brother, and we've been playing for 3 days now.

the logs arent showing the crash though, it only shows it 5 min later.

i do have a crash report i can try to share.

so like start over with a new world or copy the world and paste it in a new one?

Edit: it just crashed again, here's the log https://mclo.gs/5O0xa31
