Minecraft stuck on second loading screen

I dont know if the problem is my mod or neoforge, because i use neoforge 1.20.6 on mcreator 2024.2

I've seen that it may be because my mod is too big (200+ assets) but i dont think thats it.

To adress the bug, when i open neoforge minecraft (newest version of 1.20.6 neoforge) without my mod, it works just fine.

But when i open Minecraft with my mod, neoforge finishes loading like normal, but then a second loading screen open's and becomes stuck on like 90%

If anyone can help, please do, i've spent alot of my time on this mod and dont want to lose it.

(Sorry if i did alot of typo's, im not from America.)
