I have not found any answers or solutions to my problem yet.
Every time I try to open Forge 1.12 in the launcher it starts up normally but then when it loads the mods it won't open and I don't know what to do.
Is it because of the mods I have installed?
Mods: Wild Nature, Cubic Chunks and Better Portals.
If you know how to fix this then please, respond with how to fix it.
