Why not just grab the previous PKGBUILD version that worked?
This is why I use btrfs/snapper with pacman hooks
Instead installing older version that is either unsecure, or can cause dependency problems, I rather install Flatpak: https://flathub.org/en/apps/one.ablaze.floorp

BTW there is also the package (Bash script) downgrade to do this job. It is in official EndevourOS repositories, but also in the AUR. And if you want do it manually, head over to https://wiki.archlinux.org/title/Downgrading_packages .
