After a quick Google I discovered that ICProxy64.dll belonged to a program I'd installed many months prior called "Identity Cloaker".
I never used this program (I can't even remember why I installed it), so I decided to get rid and uninstall it. I then loaded GTA V and reset my graphical settings. The game crashed.
Luckily, it was just a one off. Since removing Identity Cloaker the game has worked flawlessly. If you're having problems playing Grand Theft Auto V (or Grand Theft Auto Online), and have this program installed, you should probably remove it... It may be just the thing that's causing all your problems.
If not, make sure you open a support ticket at Rockstar Games. They should be able to help you, eventually.
