Build #AI-182.5107.16.33.5314842, built on February 16, 2019

Steps to reproduce:
Try to open Search Everywhere (double shift) and type anything - this is a situation, when I am always getting this error (tested in few Android Projects).

I had the similar error here - now it's fixed.

@JaPawel Thanks for detailed report and tips on how to fix it! :) You can check version 1.0.1, it should be fixed now.
