Error only on first-time run: "The server "DynamicsNAV80" was unable to process the request. The application will now close."

Hello

I am currently working with Microsoft Dynamics NAV 2015 on a pos system. After starting the computer and first starting LS Nav Start, I will receive the title error (The server "DynamicsNAV80" was unable to process the request. The application will now close.) and the application closes. If I rerun LS Nav Start the program will start without error and continue to run normally.

I am trying to find the reason for this error so that I can fix it, but so far I have been unsuccessful. I have already tried deleting user personalization and this has not solved the issue. I've listed the event viewer log below:

Type: Microsoft.Dynamics.Nav.Client.NavClientClosingException

    Because you are running LS Retail - a large partner developed add on to Dynamics NAV i will recommend you reach out to your LS-Retail partner for support with this case.

    Hi, I agree with Inge, this is not a standard feature of NAV, you should contact the partner. Below are their links.

    Hope this helps as well.

    Thanks.
