Please provide your development details as below;

2. Development Environment: Unity-Android
3. Tracker/Scanner: QR Code Fusion Tracker
4. License Type: Free
5. Target Device(Optional): Realme 7 Pro

When I started the QRCodeFusionTracker sample scene I was requested to installed the latest version of AR service, however I've already installed the latest version. I've tried removing then reinstalling the service, restarting the phone .etc  yet there's no difference. The AR sample app downloaded from Google Play works fine, however.

I've used logcat to see what went wrong and it displayed: Error Unity DllNotFoundException: Unable to load DLL 'UnityARCore' on the app startup. This seems to be causing the problem. Could it be an editor related issue?

Unity Editor Version: 2020.3.26f1

ARCore XR Plugin: 4.1.7

XR Plugin Management: 4.2.1

Version control: 1.15.17
