After updating to Ubuntu 24.04 LTS from 22.04 I can no longer share my screen in chrome or firefox.
Im using Gnome (Wayland). It works on X11, but I cant use X11 due to other issues.
I have tried everything mentioned here: Screen sharing with Wayland
If I run chrome in a Terminal and select screen sharing, these errors show up in the terminal:
[25628:25628:0905/162847.590258:ERROR:base_capturer_pipewire.cc(81)] ScreenCastPortal failed: 3

Even though ScreenCast shows up in d-feet:
