Can't launch pamac-manager after update

[Invelios]

After a recent update I can’t launch the gui for updating software. I’m using the KDE version of Manjaro.

Trying to launch “Add/Remove Software” from the main Applications menu causes a plasma notification that says “Could not activate remote peer ‘org.manjaro.pamac.manager’: unit failed”.

Trying to launch via a zsh terminal gives me a different error “pamac-manager: symbol lookup error: /usr/lib/libgtk-4.so.1: undefined symbol: png_get_cICP, version PNG16_0”

pamac still seems to work fine from the command line, so it seems to be an issue launching the gui. It seems there is something it can’t find, so I’m wondering if there is a package I need to install or reinstall, but I don’t know how to figure out which one.

To replace pamac-gtk with pamac-gtk3:

sudo pacman -S pamac-gtk3

That seems to have worked, I can open pamac-manager again. Thanks!
