Status 641 means the USPTO mailed a non-final Office Action identifying issues with your application. You typically have three months to respond with arguments, amendments, or evidence. Missing the deadline can abandon the application.

The USPTO examiner has issued an office action because your requested change to the trademark drawing was considered a major alteration, your updated service description exceeds the original scope, and you need to provide information on the significance of your trademark letters.
