Wolfram Engine “No valid password found” one month after activation

It has only been a month since I activated Wolfram Engine with a valid activation key, and just now it failed. This has been a recurring problem. I can’t justify seeking Wolfram’s support again given that EndeavorOS is not supported. Any idea?

Please also note that EndeavorOS is not an officially support Linux distribution; for a complete list of system requirements and supported platforms, please see the link below.
