[BUG] - Not working on Ubuntu 22.04 - GPU process isn't usable

[pkkid]

App is not working on Ubuntu 22.04. We get the error message displayed below. I get the same error trying the AppImage or the deb install. After searching around to see what this means, it sounds like the app needs to be rebuilt with an updated version of Electron.

Trace/breakpoint trap

UPDATE: In Discord it was mentioned that using the --no-sandbox option on the AppImage gets the app up and running if you are OK running it that way.

I have exactly the same error message on fedora 35. The --no-sandbox flag also works with the .rpm version.

Same on Gentoo and running with --no-sandbox also works around the issue.

where to use --no-sandbox??

In the terminal after the filepath/filename.

Same issue on arch 5.19.13 and plasma 5.25.5, installed through AUR. Fixed by running r2modman --no-sandbox. To make the app work without terminal, find the .desktop file (usually in /usr/share/applications, usually named r2modman.desktop) and change Exec=env DESKTOPINTEGRATION=false /usr/bin/r2modman to Exec=env DESKTOPINTEGRATION=false /usr/bin/r2modman --no-sandbox.

I use r2modman --in-process-gpu rather than --no-sandbox.
