Not allowing password input.

When I press flash in balena etcher, my admin password window shows up for less than 1 second and an ad comes up for balena etcher use with raspberry pi. The add covers the password window completely and I cannot move it anywhere. I am using Ubuntu 21 and balena etcher appimage 1.7.8x64.
Please help. I enjoyed using balena etcher until this happened.

Hi, are you sure you’re using a genuine version of Etcher? You can download the official etcher version from balenaEtcher - Flash OS images to SD cards & USB drives

There are copy-cat malware versions, and we take them down as we can.
