Please double check the UIAutomator2 driver version installed on your machine, Katalon Studio works fine with version 2.10.0 and previous versions only, latest version is not supported to run for now. ![image](https://europe1.discourse-cdn.com/katalon/original/3X/3/8/3875bb1a7f683eef0726a42d556b77a2d3e21490.png) ---

Hi everyone, So I have tried to install a previous version of UIAutomator2 driver and it seems solve the problem. I am trying to perform couple of testing before closing this issue to make sure it works fine. On the other I have tried also to update Katalon to the latest version but I had an issue: ![Screenshot 2024-08-05 at 14.42.14](https://europe1.discourse-cdn.com/katalon/original/3X/2/1/21d7c59c7cc5cddb886562b5713355d6a71467e1.png) have you seen this before? Many thanks again, ---
