title: Unity3D Fail to load Dll on UWP [DLLImport] path duplicated
body: <p>I'm importing a native DLL (compiled in aarch64 release mode with make) that I import in Unity for ARM64 (Hololens2 with UWP), with the right parameters in the inspector.
  On the Hololens, the dll is placed in :
  <code>C:/Data/Users/DefaultAccount/AppData/Local/DevelopmentFiles/Template3DVS.Release_ARM64.immersion/AprilTagARM64.dll</code>
  The Dll fails to load :
  <code>Failed to load 'C:/Data/Users/DefaultAccount/AppData/Local/DevelopmentFiles/Template3DVS.Release_ARM64.immersion/C:/Data/Users/DefaultAccount/AppData/Local/DevelopmentFiles/Template3DVS.Release_ARM64.immersion/AprilTagARM64.dll.dll', expected ARM64 architecture, but was Unknown architecture. You must recompile your plugin for ARM64 architecture.</code></p>
  <p>As you can see the path to the dll is duplicated, so I presume the dll is not find by Unity... Does anyone has an idea ?</p>
  <p>Thank you.</p>
