"Native host has exited" error when I try select with Desktop Automation on Linux

After following the guide https://ui.vision/x/desktop-automation and installed XModules, maked his files executables, etc.
When I try to select the target I have this error on top of window:

This is the first crash report we see. What version of Linux are you using?

I’m using Ubuntu 19.04

Does this happen always, or “only” sometimes?

Always happens. I’m still having the problem.

I tried in Firefox and works fine.
The problem is running in Chrome.
