Start by reading FunctionUtils.java at loadAppSettingsFromSecurityStorage and WebAppConfiguration.java at readExternal, using the stack trace as the entry point. Check how the IntelliJ read action reaches the security-storage load, then verify that app settings still load without the reported non-cancelable slow-operation exception.
