MDM - GSuite Directory sync failed

MDM - GSuite Directory sync failed

Hi Team.
I have instance with connect GSuite account. I synced users from Google Workspace to MDM.
Some time ago sync failed. I apologize that password for this account was changed but i cant type new password in MDM side (( 
How i can fix sync issue ?

MDM module propose me only delete this Directory Service and re-add.
What will be with all enrolled device when i delete my GSuite account from MDM ?
