I am getting the following error message while trying to setup Unity for Microsoft HoloLens development:
Library\PackageCache\org.mixedrealitytoolkit.uxcore@45c07beda63c\Experimental\NonNativeKeyboard\TMPInputFieldNonNativeKeyboardTrigger.cs(67,42): error CS0103: The name 'NonNativeKeyboard' does not exist in the current context
This happens after I try to import any MRTK3 assets using the MixedRealityFeatureTool, how can I fix this?
I am currently using Unity v 2023.3.20f1, I have also tried on versions (2023.1.17f1, 2023.1.10f1 and 2021.3.27.f1), using Visual studio 2022 for the first 3 versions of Unity and Visual studio 2019 for the last one. Operating system is Windows 11.
Thanks

Have you checked this question: I am getting compilation errors in Unity that nonnativekeyboard could not be found.(MRTK3)? It might be that you've installed MRTK2 and MRTK3 at the same time.
Yes, I did see this, I am unclear on how to check if I have installed MRTK2 or 3, I used the MR Feature tool to install packages for unity. Can you give me some pointers on how to check my MRTK version? I don't recall explicitly installing MRTK2
You can check this with Unity Package Manager. If you can find packages named "Mixed Reality Toolkit xxx" with version 2.x.x, then you've installed MRTK2 into your project.
