Slightly unusual, let us know if the following helps:

Thanks.

After launching the game, (in my case Apex Legends, but I've seen topics with this issue in other games too) the anticheat loads up and it just gives the following errors show up:

My game isn't starting . EAC raises Untrusted system file error and terminates.

I couldn't exactly figure out what the issue is. I'm have been facing this issue for 7 days.

I tried all mentioned fixes for similar errors on other answers, but issue isn't resolved yet.

My windows 10 is up-to-date. 

I have tried this many times. scanning isn't detecting any integrity issues.

Yesterday, once I checked for updates ,it updated Security Intelligence for Microsoft defender. After that update I could play game then.

But once I stopped playing , and tried playing after few minutes same error occurred again. I don't know if its case with others.
