Installation guide recommends Etcher, but Etcher only shows a white screen on elementary OS

### What Happened?

Balena Etcher shows only a white screen.


This happened on both eOS 5.x and on a fresh install of 6.1 now that I have it installed.

### Steps to Reproduce

1. Follow the instructions on the Installation page and Download Etcher from balena.io/etcher.
2. Give the .appimage execute permissions and launch it.

### Expected Behavior

I expected that I would be able to write the disk image using Etcher as in the instructions on the web page.

### OS Version

6.x (Odin)

### Software Version

Latest release (I have run all updates)
