Linux AppImage crashes on startup

Hello everyone!

This is my first time trying to use appflowy, I am on an Arch Linux flavour called garuda linux. When I try to launch this app, it crashes with this error:

QFont::fromString: Invalid description 'Fira Sans,10,-1,5,400,0,0,0,0,0,0,0,0,0,0,1'

I am not sure if this is a distro specific issue or with appflowy, which is why I am asking here.

initially, it looks like my issue because it says that the library loading module is missing. I have installed the module, reinstalled and restarted multiple times and it has made no difference. I have checked permissions, reset caches and everything and yet It is not able to find the library. Can anyone explain why this is happening?

Hi Kavkya, can you try running the AppImage with the GDK_BACKEND settings?

GDK_BACKEND=x11 ./AppFlowy-0.7.2-linux-x86_64.AppImage

Or, install libstdc++6 which may not exist in your environment:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt upgrade libstdc++6
