Have you installed any other mods (using OpenIV to install to one of the .rpf archives) or are you just using scripts installed in the 'scripts' folder in the main GTA V install folder?
\Grand Theft Auto V\scripts
If you are just using scripts installed to the 'scripts' folder & no other mods then you are safe to reinstall the game (just save your 'scripts' folder somewhere while you do it just to be safe).
If you have installed other mods then you will need to either:
A )- Reinstall those mods after reinstalling the game
B )- Follow the process of manually finding & replacing individually corrupted archives as mentioned above.
