After Converting models, workspace won't open

Well, i was trying to create animations with GeckoLib while using a generator to create a mod in MCreator 2024.4 to the 1.16.5 Minecraft. And After just converting a model, it just won't open anymore, just it shows some message about missing "animateentity". I Tried to find backups but there is no .zip file in the workspace, neither does work trying logging GeckoLib off. Can someone help me to recover my work? I really put effort and time to create this mod and play it with my gf and then this happens.

EDIT: I was able to find how to recreate this bug and demonstrate what I did. Just click Gecko Converter and then Element Converter, both tools to the same model. Then, when you reopen your project you won't be able to. This is rather weird.
