[Solved] Cant uninstall or reinstall deja dup

[zabadabadoo]

@Tombar

I reinstalled Deja Dup using Flatpak, as the first form on the list

I am surprised you installed DejaDup as a Flatpak, ZorinOS should come with it as an apt. But I guess you unfortunately just clicked on the first package type that was listed there.
I think it bad that Flatpak was listed before the apt version, particularly for newcomers.
