Research direction

Start with the stack trace at org.fisco.bcos.sdk.network.ConnectionManager.java lines 251 and 330, then trace how io.netty.handler.ssl.OpenSsl loads netty_tcnative_windows_x86_64 during BcosSDK initialization. Reproduce the failure in the reported Windows environment and establish the required native-library behavior so SDK startup completes without the UnsatisfiedLinkError.
