More details are needed.
Please follow the top indications on each forum page: [TIP] How To Help Us Help You! (My test is BROKEN! NOTHING WORKS! PLEASE HELP ME!)
You give no info on what kind of app you test, Android iOS, what version of Katalon Studio and Appium you you use…

Specifically here, I would not go via record but actual manual step building.
Meaning that I would use startApplication, use an implicit (or temporary explicit wait) to see if it opens on the simulator/device.
When using manual Mobile Object Spy, you can use also refresh of device screen to capture objects after the splash screen disappears. This already works for many of us. Hope it will for you also.
