ITunes needs a library to continue

Hello Pro,
My iTunes is creating a problem I do not understand the root cause of this problem. Last week iTunes library was damaged so I created a new one. This is asking me to create a library every day. After that, I am facing this error repeatedly. How do I fix the error? Someone could help me to solve this error. Thanks for your help.

Choose iTunes Library
iTunes needs a library to continue. You may choose an existing iTunes library or create a new one.
