RPH loads GTA 5 but doesn't hook.

Hello everyone, last night I encountered an issue I've yet been able to fix. When I select RPH to play LSPDFR, the hook loads up, starts the game, but it doesnt hook to the game. RPH just freezes on "Launching game via Steam". The game continues to load as if I launched it normally instead of launching with RPH connected to it. 

Things Ive already tried:

  • Windowless Border/Windowed mode

  • Reinstalling LSPDFR and RPH

  • Launching GTA V then quickly launching RPH

  • Scoffline command line

  • Disabling all Plugins at startup (Only Plugins installed are EUP and LSPDFR)

Im genuinely stumped as this is the first issue I've had with this that I can't solve myself, any help or ideas, big or small will be greatly appreciated!
