I checked everything according to the above advice and I still have the same error.

In the settings/internal/com.kms.katalon.core.mobile.android.properties I have the following content:  
`{"ANDROID_DRIVER":{"app":"","language":"pl","locale":"PL","noReset":"true","deviceId":"","runningMode":"LOCAL"}}`
