Having error while changing the email address for a group

Hi Team

While changing the primary email address for a group in Microsoft 365 receiving the error as attached and with error mentioned.

The requested group 'abe42a67-df58-421a-b852-f559bb2d4074@2f3aa76a-89a8-4468-9894-2b4842b9534b' is invalid.
