Game Crashes upon Opening

Cutting to the chase, the problem is exactly as the title says. I open Marathon on steam, it says the game is running for about 45 seconds, then it stops and acts like I never started opening the game.

The BattlEye window does appear and appears normal, disappearing about 20-30 seconds after opening, ​then Steam stops saying its running 10-20 seconds later. Opening the game with Task Manager open shows the BattlEye process start, and even the Marathon process start for 5-10 seconds. The Marathon process peaks out at around 20% cpu usage before dropping back down to 0%, then disappearing completely at the same time Steam says it stops.

I've tried verifying game files, uninstalling/reinstalling, opening the game directly through its exe file, restarting my PC between each of these steps, etc. I've also reinstalled my GPU drivers, so I'm *this* close to doing a full wipe of my PC.

My specs (I know they kinda suck but they meet minimum requirements, so they should work).

CPU: Intel i7-3770

GPU: NVIDIA GeForce GTX 1060 (6GB)

RAM: 16GB DDR3

GPU Drivers: GeForce Game Ready Version 582.28
