MSIX error code: 0x80073D04

Description: ERROR_INVALID_STAGED_SIGNATURE

Cause: The signature isn’t valid. To register in developer mode, AppxSignature.p7x and AppxBlockMap.xml must be valid or shouldn’t be present. If you are a developer using F5 with Visual Studio, ensure that your built project directory doesn’t contain signature or block map files from previous versions of the package.
