Forge 1.12.2 crashing continually

[mbrad24]

Hello! If the answer to this is obvious, I apologize, I'm not the best with computers.

Basically, every time I launch Minecraft with Forge 1.12.2, it crashes with an "Unexpected error occurred, we are sorry for the inconvenience." 

This is the crash report for the launcher.

There is nothing wrong with that log. Seems the game started fine.

Post the real log from the logs folder.
