Origin: Unable to start (How do I play the game without Origin or ZLOrigin?)

I downloaded the base game and all DLCs that are actually available here right now, and when I try playing the game, I just can't. I dunno what to do, I looked for answers on existing topics but to no avail. Changing the folder's name/folder didn't do it. Also I already put the game outside C:/ drive, still the same. Running as admin doesn't change anything. Removing Origin related stuff or the program itself also doesn't do anything, neither does removing GameVersion from Documents.

Help?

What's the exact error message?

It looks like this:

Unable to start:

Origin is currently not running. Please make sure that Origin is running before attepmting to play The Sims 4

What firewall do you use? The crack needs a loopback/localhost/127.0.0.1 connection. It's a special IP address that just points back to your computer. Some firewalls are too aggressive and block that connection too. It is recommended to block the exe in firewall but you need to allow that loopback connection.

I use Windows Defender.

I also use Avira antivirus, if that says anything.

Okay, problem solved. Updating the game with the downloads from My first pet stuff to the Realm of Magic update removed the problem, maybe because of the new crack.
