NoSuchDriverError: A session is either terminated or not started

Question

I am using Appium to automate my App, when I run my code, my app crashes randomly by losing driver, and I have to run my code again, this occurs often, can anyone help me out.

Here is the error, I've copied from Appium server logs:
