What is the Apex Legends engine error?

There appear to be four main reasons behind the engine error:

  • Out of date drivers. If you are using an old graphics driver, it may need to be updated in order to remedy the issue.
  • Missing files. We know that Apex Legends is not immune to files becoming corrupted. When this happens, it can prevent the game from loading correctly, causing it to crash.
  • Administrative settings. The game sometimes needs permissions to access specific files, for example. Without these permissions, it can cause the game to crash, or lead to this engine error.
  • Windows registry settings. A missing command line, which is essential to loading the game's graphics, can also cause the game to crash.
