Usually, when games just close themselves it means they don't get enough RAM. In the requirements, it says it needs 8Gb and u have 8Gb total, but the OS will use a decent portion of it, +iirc whatever is in your VRAM will get mirrored into the RAM. I might be wrong but I'm pretty sure it needs more memory. You can increase a paging file (a file on ur hard drive that will act as an extension of RAM, but hard drive's reading speed is much slower than a RAM's and chances are ur game will just stutter) or just buy more RAM, it's the easiest and cheapest part to upgrade :') 8Gb is not enough for any modern games anyway
