So, this bug is as simple as I try to load Minecraft 17w43a or 17w43a and after the launcher closes it reopens saying it crashed! I attached the log and it just suddenly says "Stopping!"

Here is the log:

I have no idea how to recreate this as I have no idea what's causing it

Here is the launcher_log.txt (P.S. I am running it in a separate directory if that helps)
