Launcher unable to launch ModPack

[DolphinBoy]

Dear to whom may help ,

So currently friends and I have chosen a modpack to play. They've all had problems with java, ram and all the standard troubles, But my issue doesn't seem to match the normal. Everytime I click on play, it goes through standard loading procedures until it reaches the point of installing Minecraft assets. The launcher then crashes or dissapears, and proceeds to reveal itself again like I've just closed the game down. I have the launcher log attached and I hope someone can help me. I would really like to build Gastown and be a warlord to my friends . 

Also on a side note, I have reinstalled the launcher and modpack, deleted the cache, updated to the latest version of java twice, dedicated 4 gigs of ram and more multiple times. 

-Thank you for your time and consideration.
