[UWP & Device Portal] Deployment failed - Must specify an appx file to install
Unity version : 2019.4.4
I'm trying to deploy an unity UWP app to Hololens2 using device portal.
When I "Build And Run" the project in unity Build Settings window, BuildFailedException happens.
The process of building the app works fine, but I think there is a problem with the deployment process.
So if I open the built project directly in Visual Studio 2019 and deploy it to the device, deployment works perfectly fine.
This problem keeps bottlenecks in the development-test iteration process.
I wanted to see if my project source was a problem, but after creating a new project and following the hololens2 tutorial(https://docs.microsoft.com/en-us/windows/mixed-reality/mr-learning-base-02), I still get the same problem.
I don't even know what the broken characters in that error log is....
Can someone please tell me how to fix this?
