Setup Assistant errors out "Invalid sigantures from Nico Jensch"

That'd be amazing, mate. I've also tried a few other things, since posting, to no avail. Here's what I've tried...

First, here's a list of the packages that are failing for me, either through the initial setup asst, or from the "Games" tab in the "Garuda Gamer" section of the "Garuda Welcome" package.

Winetricks, Protontricks, Wine, Xone-dkms, Virtualbox, Black Arch repo...these are just the ones that I'm trying to get, there may be more.

So I found this... [Issues with “signature is marginal trust”, "signature is unknown trust", or “invalid or corrupted package”] and tried a few of these first off I tried

sudo pacman -Sy archlinux-keyring chaotic-keyring blackarch-keyring
sudo pacman -Syu

sudo pacman-key --refresh-keys

sudo pacman-key --refresh-keys --keyserver hkps://keyserver.ubuntu.com

None of this worked, so I tried to clear out the pacman keyring and start fresh with...

sudo rm -fr /etc/pacman.d/gnupg
sudo pacman-key --init
sudo pacman-key --populate archlinux chaotic
sudo pacman -Syy archlinux-keyring chaotic-keyring blackarch-keyring
sudo pacman -Syu

After borking it the first time with poor spelling, I went through it again, and successfully cleared and refreshed the keyring, but I'm still at the same problem.Thanks so much for responding.
