The upstream GParted team added a work-around to version 0.30.0 to enable it to run seamlessly under Wayland.
See https://gparted.org/news.php?item=214
Unfortunately the packager for Ubuntu decided to not use the --enable-xhost-root work-around.
See https://bugs.launchpad.net/ubuntu/+source/gparted/+bug/1737248
The consequence is that GParted only runs seamlessly on X, and not on Wayland.
If you wish to use GParted from live media, then you might consider using GParted Live.
