I am making a HoloLens 2 application using Unity 2021.3.28f1 and MRTK 2.8.3.0.
When I build my Unity UWP (IL2CPP) application with the following settings:
The Visual Studio project that is generated does not recognise the included Package.appxmanifest.
This results in the "Create App Packages..." button missing in the right-click menu and being greyed out under "Project>Publish>Create App Packages...".
When I manually add the Package.appxmanifest, the option returns but the build fails with:
"error APPX1502: The project contains 2 items that represent the app manifest: Package.appxmanifest, C:\...\Package.appxmanifest. The project can contain only one app manifest. Done building project "project.vcxproj" -- FAILED."
I have tried opening the project.vcxproj file with vscode to check any duplicate mentions of the appxmanifest, I suspected that a duplicate mention could be found in this file but there weren't any duplicates.
Can anyone point me in the right direction of what is causing this issue and a potential fix?
