@ruario Ah, so _that_ was indeed the problem! Last Sunday, my sibling and I assembled our very first home-built computer. We installed Bazzite Linux, and after setting it up, the very first application we installed for it was Vivaldi.It crashed a few times while we went through the welcome page. But after a while, I figured the browser import step was probably the cause since it was installed through Flatpak, so we skipped ahead (and voila, no more crash).
