Can you go to the help menu in the Unity Editor and click the Capture ARCore Bug Report button and attach the file it generates here? I wasn't able to reproduce these errors on my machine but this will help figure out what's going on.

Thank you for the reply! I tested on another Msi laptop and got the exact same errors. I noticed that it's the same error if you just unplug your phone and run the HelloAR in unity editor with Instant Preview. So I think v1.19 somehow doesn't detect plugged android device. Because when tested with SDK 1.18.0, it at least installs instant preview 17 app on my phone.(But depth doesn't work with v1.18)

Same here, instant preview is broken. Unity 2019.4.10f1

EntryPointNotFoundException: ArCoreUnity_setArPrestoInitialized GoogleARCoreInternal.ARPrestoCallbackManager.Initialize () (at Assets/GoogleARCore/SDK/Scripts/Managers/ARPrestoCallbackManager.cs:218) GoogleARCoreInternal.ARPrestoCallbackManager.get_Instance () (at Assets/GoogleARCore/SDK/Scripts/Managers/ARPrestoCallbackManager.cs:101) GoogleARCoreInternal.ARCoreAndroidLifecycleManager.get_Instance () (at Assets/GoogleARCore/SDK/Scripts/Managers/ARCoreAndroidLifecycleManager.cs:96) GoogleARCoreInternal.LifecycleManager.get_Instance () (at Assets/GoogleARCore/SDK/Scripts/Managers/LifecycleManager.cs:38) GoogleARCore.ARCoreSession.Awake () (at Assets/GoogleARCore/SDK/Scripts/ARCoreSession.cs:92)

This is what I get when I am trying to get AR Core logs: EntryPointNotFoundException: InitializeInstantPreview GoogleARCoreInternal.InstantPreviewBugReport.WriteOsIndependentFields (System.IO.StreamWriter writer) (at Assets/GoogleARCore/SDK/InstantPreview/Scripts/Editor/InstantPreviewBugReport.cs:162) GoogleARCoreInternal.InstantPreviewBugReport.CaptureBugReport () (at Assets/GoogleARCore/SDK/InstantPreview/Scripts/Editor/InstantPreviewBugReport.cs:105)

Also, I just tried ARCore 1.18 and Instant Preview installed on the device. Same PC

Yes same here 1.18 instant preview doesn't break that bad, it just doesn't support depth and lightEstimation (which is also not usable). But 1.19 doesn't work at all...

Hey all, this issue should be fixed in 1.20 once that is released. Feel free to reopen the bug if the issue persists.
