Running fails with access denied

I´m a first time user
When I try to run I have this error:

radzen: Generating code ...
radzen: Code generation done in 205ms.
dotnet: System.ComponentModel.Win32Exception (5): Acc�s refus�. (Access denied)

I have started Radzen has administrator
Thank you

Radzen is using .NET Core CLI to build and run the application. Make sure .NET Core CLI can work normally.
