I'm tryed to play a modpack named Gregblock, but, the modpack stoppes working during the game load, serching for the cause, i'm found that better questing is the cause, i'm launch only the better questing, and the same thing occurs.
The console log: https://paste.ee/p/XH8Gp (i'm alredy tried BQ .300)

I think that's the wrong log.

If I had to guess based on the version numbers, you're mixing the beta version of the base mod with incompatible versions of the expansion.

On an clean launch with a new profile and relese versions
its don't generete crash log
console log: https://paste.ee/p/Gbo1M

The same thing happens to me, do you have any solution to this problem?

Problem solved!
It's because of old hardware,
like, I'm used an Intel Core duo
