I have installed PnP.Framework NuGet package to read files from the SharePoint portal in my Excel Addin project (.Net Framework 4.6.1). When I debug my project locally, my Addin related code is working fine. I have bundled the entire deployment files as an executable file by using Visual Studio Setup project (.msi file). After installing the Excel Addin, I am getting below error. I have tried various approaches to resolve this issue. There is no luck still now. Could you please help me to resolve this issue?
PnP.Framework Version: 1:13.0
System.Text.Json Version: 4.7.2
