Server Error During Password Recovery via Workspaces Windows Client

Hello, I'm trying to recover a password for a workspace I created previously. I'm using Amazon Workspaces Windows Desktop client and the password recovery form falls into a loop of the "Server Error There was an error with your request. Please try again later." message. I'm pretty sure that my username is correct.

The username contains uppercase letters. I also tried typing username with lowercase letters but it did not work. Restarting the workspace through the AWS web console did not resolve the issue. Please kindly assist me. Thanks, Ismet
