Issue/Bug Description: Popsicle's CLI interface no longer displays the progress bar, or completes and closes after flashing a USB. Instead, it just hangs with no output until the user cancels it with Ctrl+C. Given enough time, flashing does complete and the USB is in the expected state, but Popsicle never terminates. It just sits at this point until killed: 2023-07-21_11-55-18

Steps to reproduce (if you know): Flash an ISO to a USB with popsicle in a terminal

Expected behavior: Progress bar is displayed, and Popsicle terminates when complete.
