A last resort guide for fixing the game crashing on startup.


This guide is a last resort for those of you who have tried every kind of startup crash fix but to no avail. Interestingly this guide is also valid if you have the same crash on startup issues with other games like Escape from Tarkov.

Crash Behavior

  • Upon launching the game the launcher instantly crashes.
  • Upon launching the game directly without the launcher the game boots up but cant pass the intro logo video and crashes.
  • Upon launching the game directly with the intro logo video disabled the game boots up and then crashes without making it into the main menu.

Affected Operating Systems

Microsoft Corporation

  • Windows 10 (Windows NT 10)
  • Windows 8.1 (Windows NT 6.3)
  • Windows 8 (Windows NT 6.2)
  • Windows 7 (Windows NT 6.1)


  • Make sure all of the game’s processes are terminated and it’s not running
  • Open the registry editor with administrative privileges
  • Navigate to the key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSet ControlLsaFipsAlgorithmPolicy
  • Double click on the word “Enabled” then change value data from 1 to 0. Leave the base as hexadecimal and then click ok. The fix is now in effect.

Note: After your gaming session is over make sure to change the value back to the default, in this case 1.

My first game was Naughty Dog’s Crash Bandicoot (PlayStation) back in 1996. And since then gaming has been my main hobby. I turned my passion for gaming into a job by starting my first geek blog in 2009. When I’m not working on the site, I play mostly on my PlayStation. But I also love outdoor activities and especially skiing.
