Device "" cannot be found

Hi Dear Team,

I face to an issue when I execute my scripts to run mobile testing, an error message pop out - Device “” cannot be found, I was executing the script in yesterday successfully. I can record my operation by using Record Mobile function, since I used and Katalon could find my virtual device. But when I want to execute script, the error prevent me. I have checked my local PC, I found only 52001 is running. Is there any way to change the port when executing script or any other solution?


Note: I just tried with Demo Script in Katalon studio, it could find the emulator and run the test. I upload two pictures, the 1st one is the message which stopped my script, the 2nd one is demo script test result.
