After MacOS Update File is damaged and can't be opened

I updated to macOS Ventura 13.3.1 today. Later in the day, I tried to open a game via Steam (Civilization VI). I had played it previously with no problems. Today, I got an error that says:

“Civilization VI.app” is damaged and can’t be opened. You should move it to the Trash. This files was downloaded on an unknown date.

I have deleted and reinstalled the app (via Steam), but I still get the warning. I've tried using the "xattr -cr" command via the terminal, but that doesn't make a difference.

Any suggestions?

If the file is already in the Applications folder, go to Terminal and type in cd /Applications.

Then run this

cp -XR 'Civilization VI.app' 'Civilization VI-2.app'

Basically it copies without attributes and copies its subtree if any.

Then try to run the new version you renamed with -2. If that works,

delete the original and use the new copied version.
