Research direction
Start at ModuleConnectorAction.java:41, where connectModuleToAzureResource is reported, and trace the call from ResourceConnectionActionsContributor.lambda$registerActions$6. Reproduce the IntelliJ Azure resource connection action with the reported environment and determine why java.util.List.get(int) returns null; done means the action no longer produces this unhandled exception.
