Stellaris Not Starting, Crashing – Quick Fixes

These issues are very common. You click the Play button in Steam, and nothing happens, or you are prompted with a black screen and unable to play the game, or simply crash. For some players, Stellaris crashes at startup or randomly through the gameplay.

If you have problems starting the game in any way, try the following workarounds:

  • Disable any user-made mods
  • Verify the game cache (right-click Stellaris in Steam -> Properties -> Local Files -> “Verify integrity of game cache”)
  • Delete the …\Documents\Paradox Interactive\Stellaris – folder on your computer (make sure to backup any saved files you may have in there)

Other methods you could try if the game is not starting or crashing:

  1. Update GPU Driver – Stellaris requires up-to-date drivers for smooth gameplay. Make sure your graphics card and other system drivers are up-to-date. For this, we recommend Driverfix.
  2. Adjust Graphics Settings – By reducing the graphics settings, you can lessen the load on your PC and keep Stellaris from crashing. To see if it helps, try lowering the graphics or resolution settings.
  3. Run as Administrator – Some launch and crash issues may be resolved by running Stellaris as an administrator. Give the game administrative rights by selecting “Run as Administrator” with the right-click menu.
  4. Compatibility Mode – If Stellaris is still crashing or failing to launch, try running it in compatibility mode. When you right-click the game’s icon and pick “Properties,” you may enable compatibility mode for an earlier version of Windows by selecting the compatibility tab.

If the game still doesn’t start after doing the above steps, then completely reinstall the game.
