Etcher asking to make changes

having some issues trying to flash an .img file to a USB drive. I get the following message: “balenaEtcher wants to make changes. Type your password to allow this.” Even if I type the password, nothing happens. I return to the Etcher screen, where the image is still selected but it is again asking for a new target.

Have version 1.5.64 on MAC OS 10.15.1

The message is expected. Can you try running it with sudo: sudo /Applications/ ?
