Hi and thanks for your help.
I have reinstalled timeshift and the error remains as you more or less predicted 
Also removing package fcitx presents a problem, maybe?
I.e. I presume you are referring to fcitx and not fctix?
I'm just not sure if I can uninstall fcitx with all these dependencies?
❯ sudo pacman -Rns fcitx
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: removing fcitx breaks dependency 'fcitx>=4.2.7' required by fcitx-configtool
:: removing fcitx breaks dependency 'fcitx' required by fcitx-m17n
:: removing fcitx breaks dependency 'fcitx' required by fcitx-qt5
❯ pactree -d 1 fcitx
fcitx

More over, maybe I am dependent on fcitx seeing this post?
I had to use fcitx-config-gtk3 to set my Norwegian keyboard after everything else failed.
See here.
Can you confirm @librewish that I can safely remove the fcitx package with all it's dependencies to try to prevent the timeshift error?
