[SOLVED, somewhat..] I need help with my mod's files compiling and it being corrupted within the gradle

I know many people have made the same post and I've checked them out down to the last forum, I found some that could work but won't, I've tried removing my cache from the gradle or the gradle folder itself, but none works. I tried restarting MCreator and such but it doesn't work, to be honest I don't really know what's going on, this has happened to some of my mods but I do not know what really, the APIs I use are: Geckolib, Curios API, and playerAnimator APIs if that will help. My mc version is 1.19.4, java is 17. I have tried other things such as the build & run -> regenerate or build gradle and stuff like that but it doesn't work too, I'm not sure why, I'm afraid I might lose everything I've worked on the past 6 months and that would be a disaster, I can't imagine what would happen after that and I can't let this mod I'm working on go down to ashes just like my other mods. If anyone needs information about this or anything, questions, software version, things related to MCreator then I would gladly provide, I'm not sure what has happened tho.

1 more, It happened after adding a 2 geckolib entities, 2 entity tags, adding a effect, and a geckolib item. I've checked the workspace folder itself to delete some extra files but found absolutely none other than 1 I do not need. That's basically all the information I can gather right now. Other than everything I've stated, I didn't do anything else.

If you could help I would be really glad!

EDIT: This was solved by updating the mod using 2023.4, It was successful but now, my blocks are the problem. It's having errors even when I rebuild it and such or regenerate, I even tried editing or making a new block to see but it was all the same. I'm not sure what's going on wrong but if possible I'd like help for this one too.
