Minecraft Crashes Instantly upon Startup

[kwstoudt 0]

My problem is this: I launch my modpack through the Twitch app, the minecraft launcher opens, I click play. All good so far. However, About 30 seconds later, the launcher pops back up with a generic game crash message:

 

Upon having this happen a few times,  I decided to start having the game output log show, which gives me this every time:

As a note, the log above is using Forge 14.23.5.2806 with all mods disabled. However, it does the exact same error even with all mods enabled and regardless of what forge version is used (including older versions of minecraft (1.7.10, etc.)

I would also like to note that the game never actually launches. Just the MC launcher and the game output window.

 

I have also tried the "Repair Minecraft" option in the Twitch App with no luck.

I can't confirm this works, but when it comes to twitch I often find going into Curse\Minecraft\Install and deleting the libraries and versions folders often fix issues with corrupted files, since it forces Twitch to re-download them.

Sorry for the long absence. Life gets busy.

 

I just tried what you suggested, and unfortunately, I got the same result.

Could you post your debug.log? It might have more information.
