For me it's frozen at -__loadActualAccessibilityBundle.

I'm not seeing this on my iPhone X running 11.2 stable.  Any ideas?

Comment 9 by srikanthg@chromium.org, Dec 6 2017 

So far not able to reproduce on any of my 11.2 devices, was able to repro on a 11.1.1 device. But am not yet planning to upgrade this device to 11.2. 
I will check back with Ramesh again and update this thread with more info.
