DllNotFoundException: InteractionSdk in samples scene

[PiteurMC]

Hi,

On a new project, tried on Unity 2021.3.43 and 2022.3.41 .
I install Meta XR All-in-One SDK v68.
I do all the project setup.
I download the samples scenes.

But when i want to launch one (TouchGrabExamples for exemple). I always have the error :

DllNotFoundException: InteractionSdk assembly:<unknown assembly> type:<unknown type> member:(null)
Oculus.Interaction.Input.Filter.HandFilter.Awake () (at Library/PackageCache/com.meta.xr.sdk.interaction@68.0.0/Runtime/Scripts/Input/Hands/DataModifiers/HandFilter.cs:144)

I have looked for hours for a solution to this problem. I have found a lot of forum posts talking about this error but no fix.

What can I do to fix this error ? 
Thank you in advance !

Try these steps from the Getting Started with ISDK page: 

1. In the Package Manager select the Meta XR Interaction SDK package and then on the right side of the window, select the Samples tab.

2. Click the three Import buttons to import the sample scenes into your project for Example Scenes, Feature Scenes, and Tools. 

Let me know if this works for you.

Yes, I know ho to import the samples scenes.

But when I launch one of this scene i have the error :

DllNotFoundException: InteractionSdk assembly:<unknown assembly> type:<unknown type> member:(null)
Oculus.Interaction.Input.Filter.HandFilter.Awake () (at ./Packages/com.meta.xr.sdk.interaction/Runtime/Scripts/Input/Hands/DataModifiers/HandFilter.cs:144)"

InteractionSdk.dll seem to be the problem but the dll exist and seem ok to me.
I Try installing all the windows updates, the microsoft redistribuable to try to fix this dll problem but othing works.

Hello, 
I have the exact same issue on my project. 
It works fine on my first PC, but got this error on the other : 
DllNotFoundException: InteractionSdk assembly:<unknown assembly> type:<unknown type> member:(null)
Oculus.Interaction.Input.Filter.HandFilter.Awake () (at ./Packages/com.meta.xr.sdk.interaction/Runtime/Scripts/Input/Hands/DataModifiers/HandFilter.cs:144)"

Did you find any solution ?

Nope sry, I have searched for hours for a solution but nothing works for me.

I haven't develop anything for VR in months largely because of this bug.

Maybe it's and hardware problem, I have a pretty old processor.

I will maybe try again one day but for now I juste stopped develop for VR sadly.

Hi, 
So if that helps, I switched machine recently and never had the problem again. Just to be sure I ended up trying on like 5 different machines and only had the issue with one. It was a workstation from a previous job with an intel Xeon so I assumed they may be some kind of compatibility issue with those, didn't dig much more than that.
