Describe the bug A fresh Unity project with imported URDF package builds an sln does throws errors and can't be used to deploy in Hololens 2.

After building in Unity, I open the .sln project but the UWP project says unloaded)

The only error shown in VS2022 v17.4.3 C:\Temp\testproject\Build-Dev\testproject\testproject.vcxproj : error : Cannot load project with duplicated project items: C:\Temp\testproject\Build-Dev\testproject\assimp.dll is included as 'None' and as 'None' item types.

To Reproduce Steps to reproduce the behavior:

1. Create new fresh Unity project Unity 2021.3.15 (all tested versions outlined below) switch to URP, set .NET Framework api compatibility
2. Add ROS TCP Connector and URDF importer packages from url.
3. Build for release, add scene, open visual studio .sln project, the UWP project can't be deployed, VS says project unloaded and VS shows error . VS2022 17.4.3

Only 1 error shown in VS output window: C:\Temp\testproject\Build-Dev\testproject\testproject.vcxproj : error : Cannot load project with duplicated project items: C:\Temp\testproject\Build-Dev\testproject\assimp.dll is included as 'None' and as 'None' item types.

5. Move URDF importer into assets/packages as https://github.com/Unity-Technologies/Unity-Robotics-Hub/issues/215 leads to same error result. After moving the folder I also made sure Unity-Robotics-Hub\tutorials\pick_and_place\PickAndPlaceProject\Library\PackageCache\com.unity.robotics.ros-tcp-connector@c27f00c6cf\Runtime\Unity.Robotics.ROSTCPConnector.asmdef includes Platform UWP
6. Moving also ROS TCP Connector package as in 5 above also continues to show same error in VS. After moving the folder I also changed Unity-Robotics-Hub\tutorials\pick_and_place\PickAndPlaceProject\Packages\com.unity.robotics.urdf-importer@https://github.com/Unity-Technologies/URDF-Importer/commit/90f353e4352aae4df52fa2c05e49b804631d2a63\Runtime\Unity.Robotics.URDFImporter.asmdef to include Platform UWP
7. Also tried Regenerate Project files but has the same error:

8. I also tried selecting Editor and UWP, but also only UWP in asimpNet.dll as per this suggestion but the same error happens.

I also tried deleting the Library, vcxproj but didn't make any difference to the error result.

Console logs / stack traces The only error shown in VS is as shown above. Unity does not show any errors when building.

Expected behavior VS sln opens so we can deploy to Hololens 2.
