sharepoint online – MS Flow is raising this error :- ‘XrmSystemUserDisabled’. Error Message: ‘The CDS system user record representing user is disabled

When the MS flow runs it raises the following error on a “Start and Wait for Approval” action:-

The request failed. Error code: 'XrmSystemUserDisabled'. Error Message: 'The CDS system user record representing user 'admin.user@***.com' is disabled. Please ask a database administrator to enable this user.'.

now the admin.user@***.com is our global admin and is enabled,,, so why the error is saying that the user account is disabled… any advice? Also seems all the Connections are working well as follow:-

so not sure what is going on?
