Game crashes about two minutes after launching, unless i get into a game and spawn, then crashes about two minutes after that.

it always pops up with anti-cheat error #000000006 when it crashes aswell

Sounds like your Easy anti-cheat service is failing

Try re-installing your easy anticheat

usually under C:\Program Files (x86)\Steam\steamapps\common\sandstorm\EasyAntiCheat unless the game is installed under a differn't drive.

Run the EasyAntiCheat_Setup.exe and it should ask to reinstall
