Minecraft Crashing from GeckoLib Entity

So I am creating a mod that has a geckolib animated entity using the plugin Nerdy's GeckoLib Plugin, and the model and textures of the entity were made in Blockbench using the GeckoLib Animation Utils plugin. In the mcreator workspace i enabled the use of api, and the model and animations i imported in the 'Import GeckoLib Model' tab. I made the entity, and put the names of the animations i made in blockbench in their corresponding slot, like 'idle' and 'walk',

and then i exported the mod for distrobution. i put it in a forge folder in minecraft, and loaded it up. It crashed and said exaclty, '(name here) has failed to load correctly.

java.lang.NoClassDefFoundError:

software/bernie/geckolib/animatable/GeoEntity'
