Hi,
Thanks for sharing here!
Would you please tell how did you configure the policy ?
Was it a user configuration or a computer configuration?
When you deploy the group policy , did you configure the security filter?
Based on my understanding , the windows Server 2019 VM and the physical machine windows 10 are in the same OU, right?
You can run command gpresult /h report.html for more details.
Best Regards,
