In case you forgot to uninstall the menu before you disable the plugin, you should encounter missing Structure and Decoration category in the
workshop menu. You can use the Fixer plugin available in Optional Files.
Install the plugin and craft the 'Workshop Menu Fixer' in chem station.
Use the Fixer chem and a confirm message should pop up. SAVE the game and DISABLE/UNINSTALL the Fixer mod.
