Edit: as Stable branch has just had a new update (2025-12-15) announced, the change to another branch suggested below may not be necessary, as all 3 Manjaro branches are now on version 9.0.6-5 of kicad. Stable & Testing are now on version 3.2.9-3 of wxwidgets-comman, with Unstable on version 3.2.9-4.
Instead of doing all of that, could you possibly try switching to Testing or Unstable branch to see if version 9.0.6-5 of kicad (built just 5 days ago) fixes the issue?

mbn can be found in the manjaro-check-repos package
Maybe the issue has been fixed with a newer build?
To switch to Testing branch:
sudo pacman-mirrors -a -B testing && sudo pacman-mirrors -f && sudo pacman -Syyu
or, to switch to Unstable branch:
sudo pacman-mirrors -a -B unstable && sudo pacman-mirrors -f && sudo pacman -Syyu
To return to Stable branch:
sudo pacman-mirrors -a -B stable && sudo pacman-mirrors -f && sudo pacman -Syyuu
Note: the extra u is required to enable package downgrades when moving from Unstable to Testing or Stable, or from Testing to Stable
