Modded Server Not Starting

[Wikip369]

Fixed Problem

Hello, I've been attempting to start up my modded server for the past server, It ran smoothly yesterday (apart from lag) and then I tried to remove a mod to reduce the lag but then the server refused to start (I didn't remove spongeforge) and it just kept saying starting and then offline. I attempted to restore a backup I made right before removing the mod but it still refused to start. Then i attempted to put it back to spigot 1.17.1 and it started and went online so i put it back onto spongeforge 1.12.2 and it still didnt work even though only the mods that Minehut gives automaticaly (spongeforge and worldedit). Then I attempted to repair files and it still wouldn't start.

Btw the server is private for me to use with friends.

Thanks, Any more information needed then I'll attempt to respond as soon as possible

Oops, so it ended with me forgetting to reset the world probably due to blocks having to be deleted from switching from 1.17.1 to 1.12.2. it probably started crashing from attempting to remove blocks from the mod.
