Anti-Cheat Incident pop up

I’ve recently got back to playing Halo MCC, but now for whatever reason, every time I launch the game after a few minutes in campaign or MP I get horrific audio cuts and stutters. The stutters and audio cuts stop when an error popup titled “Unknown file version (mcc\Content\Paks\mcc-windowsnoeditor.pak)”. I’ve already tried the following troubleshooting steps to no avail:
1.Restarting my PC

2.Verifying my files in Steam

3.Uninstalling and reinstalling the entire game

4.Reinstalling EAC under Steam\steamapps\common\Halo The Master Chief Collection\installers

5.Deleting the file mentioned in the error and letting Steam reacquire it by verifying my files
I play Halo MCC on Windows 10 Steam, and I do not have any mods or content packs installed, I only play the vanilla version of the game.

Any help would be appreciated.

Yeah i got this after trying out mods. Then decided to go back to the base game. and I don’t know how to get rid of it
