SOLUTION:
Go to C:\Program Files (x86)\EasyAntiCheat and delete the .sys file
the game should now work!
I have the same issue, deleting the .sys file just makes it come back when i launch the game and the error still exists.
The point of deleting that file is for the application to recreate it. In the past, that file has become corrupt, and thus the past fixes were to delete it and let it be re-created. However, this issue is not apparently the same with Apex. When I spoke with Tech Support, they continued to tell me that it's likely the fact that my computer specs are below the minimum system requirements they have listed. That may be the case, but it's strange that Easy AntiCheat is throwing that error message instead of the Apex Legends application throwing a more helpful error message to elude to my system specs.
