I’m using Fedora 36 KDE spin, and my Brave (snap) has been crashing whenever I type. The reason stated is “brave killed by SIGSEGV” the only noticeable change I can imagine might have caused this is changing the input method from ibus to fcitx
can you try downloading brave from .rpm or flathub flatpak
Are you using snap packages on fedora? Interesting…
You should report the bug to canonical/ubuntu.
