Failed to launch the app

Hi I am facing the following issue

Unable to start application on this device.: A new session could not be created.
(Original error: Command failed: C:\Users\Developer.Imaginnovate\.katalon\tools\android_sdk\platform-tools\adb.exe -s 8XV7N15C14000636 install “C:\Program Files (x86)\Appium\node_modules\appium\build\settings_apk\settings_apk-debug.apk” adb: failed to install C:\Progam Files (x86)\Appium\node_modules\appium\build\settings_apk \settings_apk-debug.apk: Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-insta;; io.appium.settings without first uninstalling.])

Please let me give your valuable information

I installed Katalon Studio on Windows 7 and connected with Nexus 6P with Android 8

App is installed on the device but it is not launched on it.
