Error in Java Code - driver.switchTo().window("driver.getWindowHandles() -> last name") (Error : An unknown server-side error occurred while processing the command. Original error: disconnected: unable to connect to renderer)

[description]

I want to switch to the last webview.
If you receive an error prompt when switching from Mobile Multi Device environment to Web View, please contact us.
There are no issues when switching one device to Web View. However, when switching Web View to multiple devices, an error occurs.
I wonder if testing multiple terminals under a Linux server environment supports Web View conversion.
Please check the information below and let us know how to resolve any issues we may encounter.
