Hi s. Nilothaman,

Thank you for reaching out to Microsoft Q & A forum.

Error code 0x80070005 suggests an "Access Denied" issue, commonly due to inadequate permissions. Troubleshooting entails adjusting permissions or scanning for malware.

Below are several recommended steps for addressing this matter: 

1.Run Visual Studio as an Administrator: Right-click on the Visual Studio shortcut, then select "Run as administrator". This action may grant Visual Studio the necessary permissions to access the resources essential for running the Maui Blazor app. 

2.Verify Project Configuration: Ensure that your Maui Blazor project is configured accurately. Confirm that you've chosen the appropriate target framework and deployment target, and that all requisite dependencies are correctly installed. 

3.Validate Debugging Settings: Review your debugging settings in Visual Studio to ensure proper configuration. Confirm that you're targeting the correct platform (e.g., x86, x64, ARM) and that debugging options are activated. 

4.Disable Antivirus/Firewall: At times, antivirus or firewall software may obstruct applications from accessing specific resources. Temporarily disable any antivirus or firewall software and assess whether it resolves the issue. 

5.Inspect the Output Window for Errors: Examine the Visual Studio Output window for any error messages that may provide additional insight into the issue. 

6.Utilize the Event Viewer: Refer to the Windows Event Viewer to investigate any related error messages that may illuminate the problem. 

7.Ensure Visual Studio and .NET MAUI are Updated: Confirm that you're utilizing the latest versions of Visual Studio and .NET MAUI. Updates frequently contain bug fixes and enhancements that could potentially resolve the issue. 

8.Consider Reinstalling Visual Studio: If none of the aforementioned steps rectify the issue, contemplate reinstalling Visual Studio to ensure proper installation and the presence of all necessary components.
