Viber crashing/ not working

So Iused Viber on kde plasma and hyprland, BUT I am on a challenge to use every DE/WM (i know that hyprland is a wm) and I am on Gnome and when I open Viber it ALWAYS crashes, it never loads and yeah. I am new and i used Viber from flatpak. Then (The time i am writing this June 19th) and I removed Viber (flatpak version) and installed tha AUR one (here is the link if you are interested ->https://aur.archlinux.org/viber.git) and now it doesn't even show up. ANY help is appreciated)

Re: Viber crashing/ not working

Viber from AUR is notoriously broken because it ships a very old version of Qt and bundled libraries that conflict with system libraries.

Try these steps:

1. Remove the AUR version completely:
sudo pacman -Rns viber

2. Go back to Flatpak, but run it with:
flatpak run --env=QT_QPA_PLATFORM=xcb com.viber.Viber

The xcb platform flag forces Viber to use X11 rendering instead of Wayland, which fixes crashes on GNOME Wayland sessions.

3. If it still crashes, check:
flatpak run --env=WEBKIT_DISABLE_DMABUF_RENDERER=1 com.viber.Viber

This disables the DMA-BUF renderer in WebKit, which is a common crash cause on newer GNOME versions.

Viber is essentially an Electron/Qt hybrid app that does not handle Wayland well. The xcb workaround is the most reliable fix.
