I have given logged-in users full permissions to the Project site and the Site collection administrator also had the same issue.
How to fix this issue. is this issue with client's PC that the Microsoft project installed or in Project Site?

    Hi @adil
    Before you get started using the SharePoint to MS Project sync, there are some prerequisites you need to know about. Essentially, if you are using Server or one of the Foundation versions of SharePoint, you will require the corresponding version of Microsoft Project Professional Desktop for the sync to work. SharePoint Online requires Project Online in Office 365.

    For example:
    SharePoint 2013 requires Project Professional 2013 Desktop
    SharePoint 2016 requires Project Professional 2016 Desktop

    The default field mappings you will get with the out-of-the-box sync are:
    1.Task Name
    2.Start date
    3.Finish (due) date
    4.% Complete
    5.Resource Name

    What's more, the mpp file will actually be stored in the Site Assets section of your SharePoint site which you need to check as the error says.

    Here is an article to tell how to sync Microsoft Project with your SharePoint project site for you to reter to:
