Error selected datapacks and "safe mod" thing

[LeoG]

Hello,

(Sorry for my english since it's not my primary language)

I'm playing a big modpack for a while, but stopped since i started to encounter the error "Errors in currently selected datapacks prevented the world from loading". I searched on the forum but only found 1 topic on this and it wasn't helping me.
The thing is that i have 245 mods on this, and I don't know what is causing this. I understand that maybe it's a missing mod or something like that, but looking through the logs I couldn't find what was missing ... 
I someone could help me, so i could keep my world  thanks !
I'm playing 1.19.2 on forge 43-2-8.
(Also, first time asking on a forum something like this, I hope I'm allowed to ask this here)

If you need something more, please ask me !
