Issue: How to fix World of Warcraft was unable to start up 3D acceleration error on Windows 10?

Hello. I was playing World of Warcraft and nothing seemed out of the ordinary. Suddenly, the game froze, and it did not seem like it will become responsive anytime soon. Thus, I opened the Task Manager and shut it down. I thought this is nothing to worry about as games crash sometimes and it is not a big deal. However, when I tried to open wow.exe again, the game flashed for a second and then came up with the error message “World of Warcraft was unable to start up 3D acceleration.” Since then I can not play the game, or any other one for that matter. Is there a solution to this annoying problem?
