I threw together a modpack for personal enjoyment and it opens just fine, but for whatever reason, as soon as I create a world and try to open that world, my player model and the world do not load it, I see the blank world and then minecraft crashes giving me the following as the error code and result: 
Here's the crash log. https://pastebin.com/7Seg8RT3

If anybody knows what causes this and how I can figure this out for future reference please let me know. I love making mod packs in so many versions, from 1.7.10 to 1.19.2, and issues like this just in a sense discourage me from making my own mod pack. If anybody can help me whatsoever, anything is everything. Thank you.

Seems to be SuperMartijn's Config Lib. You might want to try another config mod (Configured is my personal favorite, but you can also configure mods through Create if you have that installed).

Thing is if i'm not mistaken I got SuperMartijn's Config Lib for another mod since it was a requirement, I don't remember which mod but I can figure that out, I'll try the mod you suggested. Thank you

I don't know how that worked, or what it did, but it works flawlessly now. Thank you for taking the time to helping me out, means a lot that you did.
