OP -  Check your launch script. You have a syntax error I believe.

 

1.) Can you please go into your Mods folder and disable optifine ? Just temporarily rename it and add -disable to the filename after .jar. (that way it doesn't load up when Forge starts)

That way we can eliminate that as a possible issue.

 

 

2.) Your Launch flags are shown in the dump :

 

<//  JVM Flags: 10 total; -Xmn128M -Xmx8500M -XX:Heap//>

 

Q: Did you mean to Set Nursery heap and not initial heap ?Initial Heap is -Xms, not -Xmn.....

 

Also default  initial heap is 1G, (1024M). Java  requires you set these in intervals of 1024K or use the G suffix which is for "gigs" where 1G = 1024M. 

Java Options Doc

I would leave it default unless you have a specific reason to change initial heap. (you can just remove the -Xms / -Xmn flag altogether, which will allow Java to use the 1G initial, or you can manually set it to 2GB which I recommend for your initial Heap since you're running a Mods.

 

Also, you have manually set your Max Heap to 8500Megs or 8.5Gig. This is not a supported config and can cause issues.

 

::From the Java Doc::

Excerpt "-Xmxsize // This value must be a multiple of 1024 and greater than 2 MB!!

 

e.g. 8500 is not a multiple of 1024. This should be changed to -Xmx8G

 

 

 

If you are tuning GC you can mess with -Xmn, but I don't recommend it while troubleshooting it just adds more stuff going on in the JVM and right now we're trying to troubleshoot why you aren't loading. So leave it off while we're testing.

 

 

 

Try that change to your startup bat, and see if you get a different outcome.
