You got too many mods, try to delete as much as possible.
If this doesn't work, try to see if you're using a mod without his libary.
And if both of the above doesn't work, idk... mabey your computer isn't very good and can't run it...
I want to make Modpack for me and my friends.
I want to make the veinminer mine everything with every tool (like skyfactory or something like that), but I don't know how... I searched a lot and found nothing...
I hope u can help me.
