Why have you had to do a "clean uninstall" of Pro Tools? Especially on a Mac... this should not be needed. And how exactly have you done this?
And if you run out of drive space you never would uninstall the plugins themselves (plugins don't take much space, and they can only be in the one folder), at most you might move any separate VI sample files to a different drive/volume. Or maybe if stuff is messed up delete the VI samples and reinstall them from the installers again but placing them on on a seperate drive or volume.
For a corrupt plugin... you find what plugin is the problem and either remove it or update it with one that is not messed up.
I'm confused by what you are doing, if you have been doing standard plugin troubleshooting you would have been moving out plugins from the plugin folder... so you would know where it is, and then it's your call if you move them all out or not. If you moved them out... and you want them there you put them back... So it would be great to be a lot clearer about exactly what you have you been doing? There are certainly times where it's best to just give up and do full clean installed, macOS, Pro Tools, and all plugins but nothing besides you deleting files directly should be deleting plugins.
All .aaxplugin plugins live in /Library/Application\ Support/Avid/Audio/Plug-Ins. If you deleted those files you need to recover them from backups or reinstall the plugins.
Just reinstalling Pro Tools will not delete third party plugins.
If the .aaxplugin files are in the plugin folder but not showing up in Pro Tools then (as you do for all troubleshooting) start by trashing prefs. Get Pete Gates PT Prefs utility (
http://petegates.com/pg-pt-prefs.html) to make it easier to do this.
Do you then see the plugins being loaded in the Pro Tools splash/startup screen when you start Pro Tools? It will do that slower as Pro Tools rebuilds it's plugin index trashing prefs just deleted.
Do you see the plugins load in the Pro Tools splash screen in the inserts/plugin menus?
Also have a read of "Help us help you" up the top of each DUC web page for more info about troubleshooting.
