@Zkirky86 Your antivirus may have added a feature or become more strict at what it blocks. It's also possible that Sims 4 recently added a feature that was always blocked; that's what seems to have happened in November.
What antivirus program do you use? There are several for which people have posted screenshots of the necessary settings. Or you could check the support page for the program. And you're looking to add TS4_x64.exe as an exception, but you can only do this if it's currently installed, as in, you've done a repair and put it back.
