This code snippet for Click on add SharePoint App, continue to be loading state.

When you create a copy of master page and load it again, by default visible is set to false for DeltaPlaceHolderLeftNavBar tag as shown below.

<SharePoint:AjaxDelta id="DeltaPlaceHolderLeftNavBar" BlockElement="true" CssClass="ms-core-navigation" role="navigation" runat="server" visible="false">

Please set it to false or remove visible="false". Now you would be able to add sharepoint app without any more issue.

Happy SharePointing.
