I am attempting to compile a custom mod pack for a server I plan to host later on, however when I try to launch it goes successfully until final initialization where it then crashes. When it crashes I receive exit code -1 and when I review the crash report I find nothing that tells me what the issue is, other than that it failed to render the overlay because of an illegal argument exception.
Here is the link to the crash report and the log, in that order.

Any help would be greatly appreciated, as I'm a bit out of my depth here
