I have something slightly different. If any of y'all have the game output on, it does this thing where it opens but then the game crashes before the Minecraft window opens. However, I guess this falls into the same bug as the one reported.
I have tried Forge 1.12.2. This bug does not occur. However, with any version of Forge 1.7.10 this bug occurs. Plus, it won't let me see the crash report.
