I have updated the report and added more information.
@jakesamuels Did you do it on a server? I think that may be the issue.
I have the same issue on any 1.16 version. I am on Windows 10.
That didn't fix it for me either. Did you restart or anything? I am really curious why the log says was added to the blacklist? Like it intentionally prevents us from logging in I have that exact same thing.
This issue has not occurred in 1.18.2 as of my testing. Thank you very much! One more bug picked off Bedrock!
