I don’t recomend reinstalling it again as you’ve already tried that to no joy, however if you are on steam just check everything again, Hopefully you made a Clean GTA Backup folder, Delete all the Mods and everything then try again step by step, Install 1 Mod and try the game, Install another and try the game again, Its all Trial and error unfortunately.
But try this First!
Launch GTA5 Regular Shortcut then on the Loading screen start Rage hook separately. Hopefully this is somewhat helpful
