    Hi @DhananjaySiwach-3715 ,

    Welcome to Microsoft Q&A forum.

    Looks like this issue is caused from “Mime” side, please try to contact the author of this NuGet Package.

    I suggest you try to uninstall(if you have successfully installed it) and then reinstall it again. If this issue appeared during the installation, please directly try to reinstall it again.

    Best Regards,
