My issue is the same as yours. Problem is in new drivers. I have tried 16.9.2 and just saw 16.9.3 hotfix and downloaded it but it doesnt work too. My GTA V crashes just after load screen.
For now the best fix is downgrade to 16.8.3. You can download it from here.
I have the same problem. Latest drivers and everything. Did everything in the stickied posts to fix crashing and no go. Game will freeze, screen flickers, and game crashes. Checking event log I get the following message:
