Research direction
Start with the stack trace locations in GithubClient.java, especially getLatestAzureMcpRelease at line 103 and executeWithRetry at line 64, then inspect the GithubRelease type in the azuremcp package. Reproduce the Azure MCP Server initialization on the listed IntelliJ, Windows, JDK, and plugin versions; done means initialization no longer raises the reported deserialization exception.
