Web element reference not seen before

I have a Windows application and a web-page I’m switching between. After I have used “Open Website” -action, I cannot click mouse X/Y coordinate anymore on Window application.

The error is:
Caused by: org.openqa.selenium.NoSuchElementException: Web element reference not seen before: {“x”:513,“y”:129}

It seems that the robot tries to click to the browser, which is closed after successful execution of that part of the script. If I disable “Open Website” action, mouse click is successfull.

The script is:

RPA version is 2.4.0
