Try verifying your engine build. To do so, go to Launcher>Library>Dropdown context menu>verify to run through and replace or repair damaged and missing files. If this does not return the cable component you may need to uninstall and reinstall the editor. Thankfully as this is occurring in additional projects that does mean that the project most likely is not corrupted, which would be a more significant loss than an editor reinstall. If neither of these fixes the error, please comment again and we’ll move forward with a few additional steps that may help to show what is occurring.
