UE 4.21.2 crashes at launch

Development Programming & Scripting C++

Hi!

Some days ago, I managed to install and run UE4.21 for the first time on my computer, I even completed one of the beginner tutorials online. Then I realized that in order to program with C++ I also need to install Visual Studio 2017 on my PC, but the space on the disk was not enough. So I formatted the PC, reinstalled the OS and the drivers, reinstalled UE4.21 and now I have a problem: when I click on “Launch”, the loading window appears just to disappear one second after, then the error window I attached appears.

What could be the problem? May it have something to do with the fact that I formatted the PC? Or maybe it’s just a corrupted installation of UE4? Thanks in advice

Ok, I solved the problem by installing a driver I forgot after formatting. It was the nForce chipset driver.
