The launcher updated and reported: "The launcher has successfully upgraded, however it was not able to determine all of the game component versions. Please wait while the Launcherverifies the game installation."

It then goes to 75%, displays the message "Failed to contact the alias service [1:1:404:0]", and then sits there.

I've tried "update" and "repair", but it just takes me to the same place.
Any option but uninstall/reinstall?
FWIW, I'm on Mac.
