I have been playing Minecraft Forge (version 1.7.10) without a problem for years until now. When I try to play the latest release, I have no problem. When I try to play Forge, I get this error message saying "sorry unable to start minecraft". (I was playing it just a few days ago!) I have tried reinstalling the launcher, turning off my firewall, restarting my computer, updating java and none of these things work. I have tried everything that is suggested online, but nothing works. I have also tried launching the game on another device to try and isolate the problem, and forge doesn't even appear as a playable option. It is non-existent. How can I fix this problem? Any help would be appreciated. Thank you.
