I've been having this issue for a few months now, and have tried everything I could think of to solve it. From deleting files to updating software, the problem still persists. I've updated and removed mods, updated Java and GPU software, even allocated additional memory - but even then, Forge still continues to crash. What else can I do to help fix this?
I could only provide this Debug Log of my latest attempt to launch Forge, without any mods. I have the latest version of Forge installed. Hope this helps.
