Describe the bug

I am running Fedora and I downloaded the AppImage from the official website. The app itself works, I signed in and everything, however the "Add instance" buttons simply do not work. They are disabled and when I hover over them, the icon with a slashed circle appears.

I have checked the logs, and there's two errors which are probably relevant.
