[SOLVED] Gnome Screencast stopped working

Hi! After updating this morning, gnome's built-in screencast recording stopped working.

Before rebooting, attempting to record showed:

Screencast failed to start

After reboot, the video toggle disappeared entirely from the screencast UI (only screenshots are available).

It seems similar to these:

System Info:

gnome-shell 49.4-2
mutter 49.4-1
gjs 1.86.0-1
pipewire 1.4.10-2
nvidia-utils 590.48.01-4
Wayland session

Journal output:

journalctl --user -b | grep -i screencast

Re: [SOLVED] Gnome Screencast stopped working

At the moment, I managed to fix the issue by installing a newer version of gjs manually, as suggested in the reddit link:

sudo pacman -U https://archive.archlinux.org/packages/g/gjs/gjs-2:1.87.2-1-x86_64.pkg.tar.zst

However, I’m not sure whether this is the correct or recommended solution, since this version currently belongs to the gnome-unstable branch and not to extra.
I’m also unsure whether this might cause inconsistencies until the official package in extra gets updated.

Any clarification would be appreciated.
