I use Fusion version 1.20.1 forge.
By the way, forget about Geo and geo-fusion. It's a resource pack. It's need fusion, I dont really know what happened, it happened for my friend too So he deleted the mod and he can play the game again.

I will use other option for resource pack to play, thanks for help. Good luck!

However, without resource pack and mods it launches.

What version of Fusion are you using?

I used geo fusion, and geo. I did what it must to be, geo-fusion above just geo.

What is 'geo' or 'geo fusion' or 'geo-fusion'?
