Origin Has Encountered A Serious Problem and Must Close
I bought the base game on Steam and had been playing with no issues until a couple of weeks ago. Unfortunately my memory of how the problem arose isn't the greatest since I've been busy and putting off dealing with it. The last time that I played the game, after I closed it a window popped up which I also tried to close but missed the x and accidentally clicked on it, and I think it's caused my anti-virus to block The Sims 4. I can't remember what it said but I'm sure it was something about anti-virus. I went into avast and tried to undo it, and eventually just uninstalled avast completely. I've also reinstalled origin, and The Sims 4, and turned off my windows firewall but every time I try to launch the game, either through Steam or Origin it says 'Origin has encountered a serious problem and must close' and I don't know what to do next.
Please help!
