1.15.2 forge server crash Exception in server tick loop

[AmpArts]

I have started having issues with my server starting to randomly crash and I looked each and every "resolution with the error description: "Exception in server tick loop" and tried it all, but nothing works. I hope my friends and I do not need to reset the world and/or our characters since we are finally nearing the end game. Here are the crash report and latest logs:

I'm studying Java but I am still a novice so any help and education would be appreciated.

In the pastebin, some of the mods don't show a Minecraft version. Can you verify that all of the mods are for FORGE 1.15.2? (also make sure none are for Fabric).

Also, does the crash happen with an empty mods folder? I hate to be the bearer of bad news, but if it doesn't crash without mods, you're going to have to remove mods one by one until you can isolate the culprit. Once you find the culprit, you need to submit a bug report the that mod's developer, not Forge. Forge can't fix a problem that's caused by another mod. 

In the crash report, I see a lot of 

com.electronwill.nightconfig.

etc. in the error.

 

I can't find anything related to either electronwill or nightconfig in the mod list. This is strange. Definitely try what I said above, and ping me if you need more help!

I have confirmed all the mods are 1.15.2 and they all work in my single player MC, (Despite 2 saying they don't load), but I checked a duplicate of the server with a different world on my alternate PC and it actually runs but with no data or progress. When I transferred the world folder over is when the server started to crash on start-up. Is there a way to roll back the server by one save without it being a bukkit/forge server?

NightConfig is what Forge use for its config system. It is not from a separate mod.

Oh wait! I just realized! Take out the client side mods, such as Blur, that don't do anything on the server! I had this poroblem once. Smh for not realizing sooner!
