I've ran into an issue where Forge will freeze upon launching the game, staying indefinably in the splash screen or staying permanently in a black screen if the splash screen has been disabled. After tinkering around for the better half of the day, I've decided the issue isn't with forge itself but something on my end. I figured I'd still try to seek help here all the same.
While I have NOT tried opening a sever, these are some of the things I have already tried when launching the game;
Removing one mod at a time to see if a mod was causing an issue
Launched with only one mod at a time to see if it would even load it
Launched with no mods at all to see if it made a difference
Restarted my computer
Re-downloaded Minecraft proper
Re-downloaded Forge 1.12.2 Universal, latest, and recommended
Disabled the splash screen
Downloaded versions 1.11, 1.10, and 1.7 of Forge to see if the same problem existed and it did
Disabled the splash screen for them as well
Updated my drivers to see if they were causing the issue
What confuses me is the base game itself works absolutely fine; you can load any existing version of it and play all you want. As soon as a forge file is loaded though, it freezes.
I have also tried running other games that use java and openGL, and they work fine.
Here is the latest fml-client report; https://pastebin.com/jUp2xAvb
Again, any help, tip, or assistance would be appreciated.
