Game Won't Launch on Steam

I purchased Marathon yesterday, and the game won't launch on Steam

1. I click "Play" on Steam
2. It opens the "BattlEye Launcher"
3. The BattlEye Launcher window closes and I can see my windows cursor loading something
4. Nothing happens afterward and the "Play" on Steam button becomes available again like the game is not open

I tried every possible fix I've found online but none worked, such like:

• Reinstalling BattlEye
• Creating a new Windows user
• Enabling Secure Boot on BIOS
• Running on compatibility mode

I've seen online that old CPUs without AVX2 support can't launch the game, and that's my case. I have 16gb RAM, GTX 1660 TI and a I7-3770. Even though I am aware of my old CPU, Marathon would be the first game that won't even launch. I played recent games and they all work, even Arc Raiders.

If that's the case, I would be reliefed if Bungie would confirm this or help me out. I just want a confirmation that my spec doesn't run this game so I can ask for my refund.
