No luck. I uninstalled it via Pop Shop first, but it was still holding onto my login. So I removed it via terminal:
sudo apt remove steam
sudo apt purge steam
sudo apt autoremove
rm -rf ~/.steam
rm -rf ~/.local/share/Steam
At this point I conffirmed the steam.desktop was removed
sudo apt clean
I was able to open it to logon page and sign in. But it immediately began the flash dance. steam via Terminal does work to open it, but of course if you kill that session the app closes as well.
