App Exits after Login

I have test case recorded just for login to app, where I just login but I do  not have steps to exit the app in this test case, but when I use test case has a step in another test case, browser automatically exit out of the app after executing login, in which I do donot have steps to exit at all,  I do not want app to exit and I have other steps to execute after login, but it closes app, throw up error, it did not find the element.

Please let me know if anyone know how to solve this problem.

Thank You
