Thank you for reaching us out.
I would like to kindly ask you to generate the application log
for that failure - please clear the log, then start the test run and once the test fails, collect the log file. You could send it zipped via this thread.
What you could double check in addition is the Windows Event Viewer and what error is listed there. Please share these details as well. And if you could also send the failing test itself that will be quite helpful.
I am looking forward to hearing back from you to be able to continue the investigation. Thanks!
