The better approach here will be you to open a CA Support Ticket and then we can help you to rebuild your UMP Server back!
Not sure if just deploying the wasp probe from your Archive to the UMP Server will work!
Maybe will need to install if from scratch to do not have any other's side effects for other issues.
If you have a VM Snapshoot, please do the Rollback.
Kind Regards,
