Start by reproducing the SEH exception when initializing the embedded App with Windows Store Python 3.14. Then inspect the App initialization path and the existing conditions for the Windows Store workaround mentioned in the report; done means initialization no longer raises the exception and the conditions cover the reported Python path.
