Something went wrong while installing: java.lang.NullPointerException


Recommended Posts

Im currently trying to install forge to play some mods that are only avilable in 1.16.5, and since I would like it to work with OptiFine I downloaded the 36.1.0, installer, it didnt work, so I downloaded the recommended one, it still didint work, maybe the latest version? nop, will still not work, downloaded some more random versions that werent the ones I needed or recommended and it will still crash telling me "Something went wrong while installing: java.lang.NullPointerException"

I keep trying and searching answers for this problem but they will just not work, I dont know what to do, and each answer is completely different, I dont understad why it doesnt work. I would really appreciate if somebody could give me an answer, if it works thanks, if it doesnt well at least you tried helping, thanks!
