Can not run PixelStreaming in Standalone

I have PixelStreaming plugin enabled in my project. When I use Play - Selected Viewport, plugin does not work. Nothing in logs and I guess it does not load at all.

When I try to use Play - Standalone Game, I’m getting errors like:

It looks like this plugin works only when you package project, but packaging is expensive and I need to debug some blueprints. Any ideas how to solve it?
