I searched for a couple of hours and found this answer on another thread. I am posting it her to hopefully save my fellow Sim-ers some time!
''The instructions finally worked for me. For whatever reason when I did it the first time it did not add. The video below gives the same instructions and it works.
Go to Windows Defender Security Center
Click Virus and Threat Protection
Click Virus and Threat Protection setting
Click manage controlled folder access
Click allow an app through controlled folder access.
Add an app
Go to C:// Program Files (x86) > Origin Games > The Sims4 > Game > Bin and add TS4_x64
I added both TS4 and TS4_x64 just in case."
It worked! My firewall was blocking the game.
THANK YOU SolangeSoleil !!!!
