Fix for Apps and Games (including VR) made with UnrealEngine that do not start on newer processors

Some apps created using Unreal Engine do not start on PC on CPUs newer than 2018. It happened to me in many VR apps and games. They only run for a few seconds and then just close without any warning.

The fix for this is to create a system environment variable called “OPENSSL_ia32cap” with the value “:~0x20000000d”, both without the quote marks ["].

Here is where you should set this and how it should look like:
