Hey titantechsupport,
Welcome to Apple Support Communities.
Are you using M1 Macs? If so, the screen saver will activate after 10 minutes. The only way to resolve to resolve the issue is by going to the actual remote Mac and restarting it.
If you would like to submit feedback and/or suggestions about this to Apple, click here: Product Feedback - Apple
If you have further questions or concerns Apple Remote Desktop, contact Apple Support Business and Education Support here: Get Support Search for "Apple Remote Desktop" in the search field. This should then direct you to support options.
Take care.
