Server keeps crashing, need help asap

So my server doesn’t wanna start, it crashed while it’s opening in command prompt. I tried replacing and deleting and renaming level_sponge_dat_old and level.dat and level.dat_old .
Really pretty much all of these. I placed my 2 week old server world into my single player saves folder to try and run it and it said human missing need to make a backup of the world. Mc did it themselves and i got into the world in single player. It began to lag a lot but after some time I was back into 60ish fps with some drops here and there. Me and another person who played on the server with me for sure didnt do anything in the world. like we didnt placed something that was crazy or outside of a modpacks intentions so I’m not sure why the world is causing the server to crash in command prompt. I’ll leave my latest crash report here and I’d appreciate help. Also I forgot to mention that if I remove the world file for the server I was able to run the server and join the server but obviously I’d have to start all over and it’s a big deal since we built a lot. So id like to use that world and not make a new one.

This is the same error like here: Server Errors (Won't Start Up)

When I delete the file or rename it, once i start the server it just creates the exact same file in the same area idk what im doing wrong

Maybe you can try to update SpongeForge to a newer version and than delete the file and try that again.
(Since the changes fixing the error are not in your version)

I have the latest recommended SpongeForge. Which one do I get then

The recommended one is 2 months old
https://www.spongepowered.org/downloads/spongeforge/stable/1.12.2
Below ALL BUILDS are newer ones. Yes, they are not “recommended” but maybe it fixes your error until a new recommended build is available.

Do I just download one and replace my previous spongeforge in mods folder for the server and then delete level_sponge_dat or what? Because I just did that with 2 different versions of spongeforge and stil the same problem?

Sir if you have skype id appreciate a call so I can show u my screen, all of this is weird

Well you described exactly what i thought you could try, if it does not work i have no further idea, sorry :frowning:
Maybe someone else tho… ^^

Are you restoring the correct level_sponge.dat file? It’s the one from DIM-1 that’s corrupt according to the error:

Just to let everyone know, this file corruption is a known issue. I have a possible fix for the corruption that will be in the next recommended build.
