What bugs were found in Jason's source code, and how were they fixed?

The source code had four main bugs: a certificate trust policy issue in `Form1.cs` where the lambda syntax was incorrect; two variable assignment errors where results were not stored back to variables (e.g., `MainConfig.AppLocation + "out.txt"` needed to be assigned to `MainConfig.AppLocation`); and a bug where `MainConfig.Method` always remained empty because it used `SelectedText` instead of `SelectedItem` for the combo box selection. These fixes restored normal functionality, allowing successful compilation and operation.
