The game crashed whilst initializing game

[Nexo02]

Hey guys.

Im trying to set up a modpack for 1.15.2 but I ran into several errors. First one was caused by the pre version of Optifine so I assume that there is no mod compatible version yet?

Second is the error listed in the title. The full error is: "The game crashed whilst initializing game Error: java.lang.NullPointerException: Initializing game"

I tried without several Mods and also changed the forge version but without any success. So I'm asking you guys for help know.

 

The debug.log is attached below.

First, thanks for your Support.

I tried removing some Mods including MobEffects and Sound Control.

With a little bit of trial and error everything works now so a big thank you from me.
