When trying to browse data from OPC Server, we get a "Browser isn't attached to com object" exception. While debugging we notice that https://github.com/titanium-as/TitaniumAS.Opc.Client/blob/77e34b6cea1b083294042ffd69b10696733d366f/TitaniumAS.Opc.Client/Da/Browsing/OpcDaBrowser3.cs#L43 returns always null

note: we use net6.0 as framework

problem was related to the OPC Core Component - it require v3 and produce this behaviour with v2
