My addons reset please help

all of my garrys mod addons broke and they all say “failed to install” my main hard drive broke in february but i had the game installed on my other drive? can i fix this issue and if i can how do i fix it

Try to use the factory reset tool in the “GarrysMod” folder of your game. It will erase everything to give a clean copy of the game, so you can test if it works again.

i already did that theyre still broken
