This works for me as in I can now use yay to get AUR packages but I still don’t know how to get the AUR tab back on pamac.
I think that earlier today, there was a pamac-aur or pamac package that failed to update, while everything else updated normally. Once I rebooted, the (failed) update entry stopped appearing. Now there is no AUR on pamac. Which made me think that pamac was stopping support for AUR as a whole.
Is there a way to reinstall pamac entirely? I haven’t managed to rebuild from git, due to conflicts. So I might need to uninstall it completely. I don’t know how sound that is though.
At any rate thank you. I managed to save my grub some other time thanks to the advice you are giving here
