Hi,
Do you provide the correct locator of the box you want to check? Please try to check the locator manually to make sure it is visible and clickable. If you receive any error log, please provide us. In the meanwhile, more information from doc Locators and Object Identification in Katalon Studio | Katalon Docs or some other discussions (Root cause: Object Object Repository/test/mytext not found) - #5 by Chris_Trevarthen or I can't spy or record on android mobile might be helpful.
