My preferences will not launch properly. when it does i only get general and presets, everything else is blank. i have reinstalled lightroom and rebooted my mac but it still does the same. any suggestions?

Try resetting the preferences of Lightroom Classic:  https://helpx.adobe.com/lightroom-classic/help/setting-preferences-lightroom.html 

  

Backup your preferences prior to resetting the preferences:
