I have the same problem. Even tried with Blizzards UI and no add-ons on my character that’s the GM of my bank guild and still can’t withdraw but can now deposit.
Same problem here. Guild bank says I’m not in a guild, but I am however still the Guild Master and we still have guild members. Problem was solved on 2 other servers but not yet on Argent Dawn.
Same for me too
