Windows 11 has a feature called Smartapp control which verifies the signatures of various software that you install on the computer prior to installing it. Mullvad gets blocked. Has anyone else had this issue before?

This is basically what smart app does: Smart App Control knows that what you’re using is safe but isn’t able to make a confident prediction about the safety of the other file your app opened so it attempted to verify the publisher of that file by checking its signature. The file isn’t properly signed so Smart App Control has blocked it.
