Engine won't start - Nvidia problem?
Please help – not been able to do any development for 3 weeks.
I have been happily using an Acer Predator laptop for development for over a year. I had the Windows 10 April 2018 update a few weeks ago. Instantly I was unable to use Unreal 4 without suffering issues with very dark colours. Also impacted my game of choice: World of Warcraft which wouldn’t start at all! Rolling back the update sorted all the problems but obviously this is in no way a solution.
With the help of a friend and some research the problem appears to be a Nvidia driver and Unreal conflict. I have taken the following steps to try and resolve the problem: • Uninstalled and reinstalled the Epic Launcher and Unreal 4.20 – had to use the Microsoft uninstall tidy-up utility: https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed • Uninstalled and reinstalled the latest Nvidia driver – GeForce GTX 970M – using DDU • The Nvidia control panel on the laptop has limited options
Now the launcher is fine but Unreal Engine will not start at all. Instead it launches the crash reporter which then crashes itself so it cannot even be viewed. (WoW now works though!)
So I am stuck. I do not want to restore to the previous version of Windows 10 again as this sort of problem will simply recur at some point.
I am sure I am not the only laptop user that has had this problem. Please help!!!

I found a solution to my crash. All I had to do is make a shortcut to the Unreal engine on my desktop, in the shortcut's properties, at the target field, I added a space followed by -DX12 (This is case sensitive).
Unfortunately, this is not a perfect solution and seems to not work for everyone. It does make the editor work if you use a shortcut from the Desktop but the same problem still occurs when you launch the game form the Epic Launcher. Another problem that still exists is the moment you try to debug your code from Visual Studio the engine goes nuts.
Since then I formatted my Laptop with a clean install of Windows which fixed all my problems. I do realize this will not be possible for everyone though.
