This is an issue I've seen some other users reporting. Whether I launch the game with Anti-Cheat disabled or with it enabled, either way I cannot play multiplayer. When I attempt to do so, a message pops up saying how the custom sound file is being flagged by Easy Anti-Cheat. The only way to allow multiplayer is to delete the file and verify integrity of game files. While I can do this, I'd much rather keep the mod and just be able to do have both. Surely there has to be a fix or method to bypass this?
