Winesteam stuck on "Update"

Hello, I’ve been using Lutris sparingly due to (native) Steam working mostly fine for me. Now that I want to play Batman: Arkham Knight (which doesn’t work on Proton but works on Wine+DXVK apparently), I am trying to get WineSteam up and running. However, on setup, I always get stuck on this particular “checking for updates screen.”

If I try again I sometimes get a “FATAL Error: Steam requires an internet connection to update”

Here is the debugger log when I attempt to run the install-
