Hi,
Thank you for posting your issue to our Q&A forum.
I understand your problem is that you could not successfully install the .appxbundle package generated by Windows Application Packaging Project in Visual Studio on your Win 10 laptop.
If so, please kindly follow the troubleshooting steps in below article to see if they could help to resolve your issue.
Troubleshoot installation issues with the App Installer file
- You can first check if the Developer Mode or Sideloading apps has been enabled on your laptop.
As per this article Enable your device for development,
if you are writing software with Visual Studio on a computer for first time, you will need to enable Developer Mode on both the development PC, and on any devices you'll use to test your code.
- Also, you can try to install the file using Add-AppxPackage PowerShell command to have a test.
There is also another article you can refer to for installing .Appx or AppxBundle Software on Window 10.
