MCreator Gets Stuck On Loading Screen

Whenever I try to run the client, it freezes on the Mojang loading screen, and always at the exact same point on the progress bar. This started happening after I installed the GeckoLib plugin for MCreator and stopped when I removed the plugin. I've seen other people make posts about this issue, and some of them got resolved, but nothing they say to do in those posts worked for me. I've narrowed it down to the plugin itself, not anything with the entity, as the error still occurred when I deleted all the animated entities and models in my workspace. Help ;–;
