My modded server keeps shutting down a few seconds after I join it. I need help

[frostyblizzard5]

A few days ago i saw a post here that explained how to use spongeforge to play mods with minehut, and it worked for a little while but now my server keeps shutting down after I join it and can't figure out how to fix it. When I looked in the logs it said this:

[01:14:01] [Server Watchdog/FATAL] [net.minecraft.server.dedicated.ServerHangWatchdog]: A single server tick took 6.00 seconds (should be max 0.05)
[01:14:01] [Server Watchdog/FATAL] [net.minecraft.server.dedicated.ServerHangWatchdog]: Considering it to be crashed, server will forcibly shutdown.

the mods im using are: Aether, betterfps, bookshelf, BrandonsCore, Buildcraft, CodeChickenLib, Draconic Evolution, Enchanting Plus, Hats, iChunUtil, ironchest, just enought items, morph, Redstone Flux, spongeforge, and twilight forest. Theyre all the right version, 1.12.2

Does anybody know how to help me with this?

I am having the same problem but only when I join not when other people join, I think the chunk my player is in is a corrupted chunk. If you have any backups try using those
