[Quest] Freeze at splash screen - OPENGL NATIVE PLUG-IN ERROR

Hi.
Following the setup from here (

) and the app is freezing displaying the splashscreen.
I am using Unity 2019.2.3f1, Oculus Unity plugin 1.40, Oculus Android 1.38.3.

Any ideas why?
Thanks!

In the logcat I see:

Apparently, the OPENGL NATIVE PLUG-IN ERROR comes from Multithreaded rendering.
