couldn't find the 40.1.42 version in official forge site , will try the next version which is the 40.1.44 under that there's only the 40.1.41.
Will reply if it was a fixed or gave another error.
Hi, saw a bunch of other people having the same problem but i figured it would be best to paste my crash log, worth mentioning i'm using an alternative launcher "SKLAUNCHER"
