1) Did you upgrade power automate?
If so try reinstalling the extension. I had this issue for the update prior to the current one and had to update my extension
2) Are you using power automate virtual desktop or Window Server?
I have noticed that when I have multiple screens up, if I try to hide the window that power automate is running in for my local machine, power automate will stop running and throw this error. It as if hiding the browser hides the visibility or enters an interrupt. Power automate is very different from Selenium where I could step away and work on other stuff while waiting for a 3 different 2-hour web testing and web scrapping script to complete.
I really should report this a bug. But I am not sure how to report it.
If its neither option 1 or option 2, then let me know. I have a few other ideas about what might be the cause.
