"java.lang.reflect.invocationtargetexception:null" error 2023.1

So i'm using 2023.1 from more than a year now working on a mod.

Just today i added a new procedure and everything and didnt do anything different but when i use mcreator to launch minecraft, it gives me the "java.lang.reflect.invocationtargetexception:null" error.

I searched abt it and the issues i saw where with geckoLib mod or plugin, but i never used it or even used a plugin ever, and the problems i saw were resolved by the adding the mod or the plugin, while it dosent work for me because i never used or put a plugin.

I use blockbench for models and it never really gave me an error about it, it worker ever since.

I have no clue whats the problem
