Hello! We've received several reports about a problem after the last update and our engineering team is investigating the issue. As a workaround go ahead and sign out of the Mozilla VPN (you can do this by going to the gear icon on the top right of the application, then scrolling down to "Sign out"), uninstall it, re-download it, and reinstall it. The sign out is an important part of the process due to deleting some files that otherwise don't get purged. This should solve your update issue,
