As of today, I have not yet solved the issue, here's what I have tried so far:
• Alt account.
• Checked the console before the game crashes.
• Changed performance and screen settings.
• Re-installed the game.
• Re-installed the launcher.
• Re-directed the game file to a wrong directory, then correcting it.
• LAN mode.
• Multiplayer and zombies custom and online matches.
• The "xpartygo" command.
• Optimizing the launcher with windows graphics custom settings.
• Prayed God.
• All zombies maps + some multiplayer ones.
• Messing with different plutonium files, but ended up re-downloading anyway.
