This looks like a sandboxing issue. Using the “no-sandbox” flag has never worked on AppImage from what I remember, except for very light runtimes. Running with sudo will throw that error because the root user has no display manager running.
Just try running the installer if you don’t want to mess around with debugging the AppImage. Check the GitHub Issues for related keywords and see if others are running into the same issue, maybe it’s just a specific release, or SELinux causing the problem.









They have a simple bash installer from what I see. You can also install everything via pip as well. Couple quick commands.
That bug report mentions a few versions, so maybe just go back to whatever version was working on your other machine.
