[MCL-10060] Game crashes on startup with "monitor Process crashed with exit code 6"

Game crashes on startup with error message "An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience."

Upon running the output log, the following process comes up

00:17:26	launcher	Preparing to launch minecraft client for 1.13.1
00:17:32	launcher	Checking installations.
00:17:32	launcher	Minecraft client 1.13.1 is ready to start.
00:17:32	launcher	Starting!
00:17:32	launcher	Using default game log configuration client-1.12.xml (outputs XML)
20:17:33	monitor	Process crashed with exit code 6

I can't find anything regarding exit code 6 online. Any suggestions? I have a world that I have been working on for 6 years that I would like to be able to access.
