Ive been playing skyfactory 4 for a few days with no problems at all. today i try to launch it today and nothing happens, have reinstalled the launcher multiple times and also reinstalled java (1.8.0_451) now i cant install any modpack. have also tried running launcher as admin, didnt help. there seems to have been a launcher update very recently, not sure if its that causing the issues.
this is the console error i get
[B#946] java.lang.NullPointerException
