Not really clear to me what happened.
You removed pamac-all → ok a dependency was broken
So you managed to update → ok
Of course now you don’t have pamac-all anymore, if this is what you mean with “store”.
Luckily, it looks like they fixed that broken dependency (libpamac-aur), so now reinstalling pamac-all should work.
paru pamac-all
I say “should” because I’ll never use that stuff…
