While uploading our UWP app (Edtech Gaming) on the Microsoft store which we developed using Unity platform, it shows error with the below info :
Error Details: Supported APIs Error Found: The supported APIs test detected the following issues:
- The API CoInitialize in ole32.dll is not supported for this application type. Audio360.dll calls this API.
- The API PropVariantToInt64 in propsys.dll is not supported for this application type. Audio360.dll calls this API.
Impact if not fixed: Using APIs that are not part of the Windows SDK for Microsoft Store apps violates the certification requirements for the Microsoft Store
Do we have any alternatives for "CoInitialize and PropVariantToInt64" APIs are unsupported in the Microsoft Store UWP apps. What are the alternatives to for the above APIs.

Welcome to Microsoft Q&A!
CoInitialize and PropVariantToInt64 are only supported on desktop apps.
There is no API in UWP that can directly replace "CoInitialize and PropVariantToInt64". PROPVARIANT is supported in UWP, what are your scenarios for using these API? Maybe we can solve this problem from other direction.
Thank you.
