Send SMTP Message Freezes UIPath and Does Not Run

I am trying to run a very simple process to send an email however when hitting run on my process it freezes UIPath, appears to be running but never executes anything. It then does not allow me to stop the robot from running.

I have tried uninstalling the Mail package and re-installing but have had no luck.

Do you have any suggestions please?

Thanks in advance.

attach the workflow for review

Please find attached my workflow. I have changed the email to a test email and have not entered credentials for confidentially.
