The UE4 editor crashes every few minutes, first noticed when I tried to run a C++ project with some changes I included. But after that I have tried a normal BP project without any changes, it still dies in few minutes.

I tried both the version 4.17 and 4.15, same issue “D3D device being lost” comes and crashes my UE$ with a hung window if I don’t report it. Kindly request any one to help. I am desperate to get this working

System Details:
Windows 10
16Gb ram
AMD Radeon
Intel graphics 620
HDD 1tb

Thanks for your time,

Best Regards,
Raj

The issue was with the AMD Radeon driver i recently upgraded, once i downgraded it everything went fine. The version i have is the one that was released on 03- Sep-2016. The version numbers are different on the site and different in my system. So its better to go with the date.
