My friend is unable to launch the game!

Hi! We have gone through a large number of various troubleshooting steps, including, but not limited to, all of those mentioned in the following article:
When starting the game through steam, it simply does not open. Steam seems to think it is; however, a scroll through the detailed task manager list makes it clear that it is open neither as an app nor a background task. When closing completely out of steam, going directly to the game’s .exe in the local files, and running it as administrator opens it as a background task consuming precisely 112.0MB of memory (This increased by 0.2MB every so often before dropping back down to 112.0MB). Running the .exe also runs steam and the moment steam finishes its startup process and it opens as a window, second extinction disappears from task manager completely.
Any help would be much appreciated!

CPU - AMD Ryzen 7 3750H
Memory - 16GB DDR4 @2400Mhz
Graphics Card - GTX 1660 Ti
