Try the following steps it worked for me.
Log completely out of Facebook Gameroom. It runs in the background so make sure you completely log out of it. Check under your hidden Icons by the clock.
Disable all your antivirus including windows defender.
Launch SWC and it should update automatically (at least mine did)
Enable all your antivirus protections (if you are not sure just restart your PC they will automatically start on a reboot)
I did this 2 days ago and has been working for me ever since.
