I have not been able to reproduce the bug. If there are additional steps for reproducing the bug I should be aware of, please let me know.
In the meantime, are you able to edit English Wikipedia normally? Your account isn't blocked but it is possible that you are using an IP address that is blocked, or autoblocked.
I commonly have "Add archives to all non-dead references (Optional)" activated. If you tested archiving Team17 without this, it will have not produced an error because no changes were made.
As for being blocked, I just sucessfully edited the article Epic Games, but then tried to archive it (with non-dead refs on) to no avail.
Reopening as the issue is occurring again. I first observed it today trying to re-archive Robert A. Altman (with non-dead refs enabled). I was able to use the tool fine yesterday and nothing has changed about my account status. As before, an archive run that would make no difference does not return the issue (likely as no edit is attempted).
