Error message:

IdeaLoggingEvent[message=null, throwable=java.lang.IllegalArgumentException: Cannot add an action twice: Upgrade Java Runtime and Frameworks (Upgrade Java runtime and framework versions) (com.microsoft.azure.toolkit.intellij.appmod.javaupgrade.action.JavaUpgradeContextMenuAction)

Start with the stack trace in UpgradeActionRegistrar.java, especially tryAddToGroup at line 100 and discoverAndRegisterAction at line 63, then inspect JavaUpgradeContextMenuAction registration. Reproduce the IntelliJ plugin error and verify that the Upgrade Java Runtime and Frameworks action is registered only once without an uncaught exception.
