If you are attempting to launch Apex Legends from Steam and being hit with the untrusted system file error, which is caused due to the Easy Anti-cheat system used in Apex. Thankfully, there is a fairly straightforward fix.

Although this specific error has been around in Apex Legends since launch, it has reared its head again a lot more frequently since Apex was released on Steam. But, it can also still affect players on Origin.

What is untrusted system file on Apex Legends?

This error is caused by Easy Anti-cheat flagging certain game files as ‘untrusted’. It is a measure to prevent players with hacks and cheats loading up the game, but it can also sometimes incorrectly flag perfectly normal files.
