My game crashes when I spawn an entity

Hello to all,
I have been using the geckolib plugin for a long time and something regrettable has happened to me.

I made a mod with 173 elements in my workspace and I lost everything due to a bug. Indeed, everything worked well with my plugin and my animated mobs and overnight the personal mobs that I was doing spawn crashed my world. In the end, all my entities were deleted and now I can no longer get geckolib to work no matter if I created a new workspace or on existing ones. I have tried uninstalling Mcreator and reinstalling it. I even went so far as to reset my PC and nothing to do. I still have this damn bug that crashes minecraft every time I spawn an entity.
