According to the error info, you are implementing with a not exist namespace.

You can use tfssecurity /a command to view a list of namespaces at the server level

The namespace that contains the group from which you want to remove the user or group. You can also use the tfssecurity /a command to view a list of namespaces at the server level, the collection level, and the project level.
