[02gaurav]

Describe the bug
Exception while clicking on some button, its asserting visibility correctly. Also, navigation is fine on tapping button. But after tapping on the button got this exception and remaining test cases got stuck.
Exception in thread "pool-4-thread-1" java.io.IOException: Command failed (tcp:7001): closed

at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:630)

Expected behavior
There should not be any exceptions and test cases should not stuck.

I'm experiencing this same issue on Maestro version 1.31.0 when running most Android 10 devices:

The second exception above occurs when I Ctrl+C after the first exception stops the flows from continuing.
