Error #101: UI.Vision RPA is not connected to a browser tab

Has been mentioned before, but developers were not able to recreate it so far. I’ve found a way to consistently recreate it on my computer.
Command: selectWindow | tab=0
Error #101: UI.Vision RPA is not connected to a browser tab

Steps:
I have the Firefox browser open and several tabs
I have UI.Vision open
I go to CSV and open the CSV editor on one of my CSV files (it opens in a new Firefox window)
I close the CSV Editor
Now when I run my script I get the error
I go to Firefox and switch to a different tab
Now when I run my scripts it works

Hope this helps.

Thanks for this helpful post. But I have trouble recreating it. => Can you please record a screen video of these steps? Thank you!
