Signing process

Hello there,
I was using zatca sdk
zatca-einvoicing-sdk-238-R3.2.4\Lib.Net\SDKNETFrameworkTest\SDKNETFrameWorkLib.dll

and It works very good;

these days we deiced to use last available sdk, so we use version 3.3.5 which is based on .NETFramwork 4.8. I try to make demo app to test new zatca sdk version and I got the error that telling the verifing signed xml file is invlaid this is the visual basic Code

Sub Main()

    Dim vCert As String
    Dim vPvKey As String
    Dim vXmlDoc As New XmlDocument()

    ' This certificate and privatekey are copied from Folder: zatca-einvoicing-sdk-238-R3.3.5\Data\Certificates
    vCert = "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"
