My game crashes while loading.

[gabkat]

I click play on curseforge, it brings me to the MC launcher, I click play like normal and it gives me an error: 

The game crashed whilst initializing game Error: net.minecraftforge.fml.ModLoadingException: Sophisticated Backpacks (sophisticatedbackpacks) encountered an error during the common_setup event phase

I tried reinstalling the mod, then deleting it completely, and nothing worked, it just brought up a different mod in the error. I looked it up online and saw people saying to uninstall optifine, so I did that and it still didn't work. I also made a new instance thinking it would fix it (it didn't).

I don't know much about this stuff but here is my crash report:

Looks like sophisticatedbackpacks is conflicting with vanity
