Randomly started getting DllNotFoundException error when building AR app for iOS,Building AR app for iOS, everything was working but now the AR element is not and I am getting this DllNotFoundException

Not sure what happened, my project was building to iOS just fine then randomly the AR element stopped working (my build wouldn't use my phone camera, just showed default unity 3d background) and now I am getting this -

DllNotFoundException: Packages/com.unity.xr.windowsmr/Runtime/Plugins/x64/WindowsMRXRSDK.dll UnityEngine.XR.WindowsMR.WindowsMRSessionSubsystem+Provider..ctor () (at Library/PackageCache/com.unity.xr.windowsmr@2.6.1/Runtime/Session/WindowsMRSessionSubsystem.cs:28) UnityEngine.XR.WindowsMR.WindowsMRSessionSubsystem.CreateProvider () (at Library/PackageCache/com.unity.xr.windowsmr@2.6.1/Runtime/Session/WindowsMRSessionSubsystem.cs:21) UnityEngine.XR.ARSubsystems.XRSessionSubsystem..ctor () (at Library/PackageCache/com.unity.xr.arsubsystems@2.1.16/Runtime/SessionSubsystem/XRSessionSubsystem.cs:77) UnityEngine.XR.WindowsMR.WindowsMRSessionSubsystem..ctor () <0x149ff5030 + 0x0004a> in :0 System.Reflection.MonoCMethod.InternalInvoke (System.Object obj, System.Object[] parameters) (at :0) Rethrow as TargetInvocationException: Exception has been thrown by the target of an invocation.

Does anyone have any idea what this means? I am new to Unity and AR Foundation

Here is what I'm getting:
