Research direction

Start with the reported stack trace, especially AzureTelemetryClient.java, AzureTelemeter.java, and AppModUtils.java, and inspect how the telemetry call reaches the IntelliJ EDT. Use the listed IntelliJ, Windows, JDK, and plugin versions when investigating the freeze. Done means the reported EDT freeze is understood and no longer blocks the UI during this path.
