Hi Green Bray Games LLC,
I'm not sure this is the right forum for this question, but this might solve your issue:
"Local Machine will deploy the app to your current development machine. This option is only available if your app's
Target Platform Min. Version is less than or equal to the operating system on your development machine."
https://docs.microsoft.com/en-us/windows/uwp/debug-test-perf/deploying-and-debugging-uwp-apps
Let us know if that does/doesn't help.
Thanks!
