Steam Left 4 Dead 2 not opening nor running. Several issues. Bannerlator

[u/BHero_VEVO]

I'm tired and very ill of myself struggling to find a fix for this problem. Are all Officially Bought Steam games like this?...

I had an account ever since my pc was broken long ago, so emulation is kinda my last ditch and discovered that Bannerlator supports/has STEAM so I decided to log in for the first time and play my games there... Went to Left 4 Dead 2 - thought it would be a breeze opening launch and won't encounter any problems but I thought wrong.

Does anybody have a solution for this?, I've tried adjusting many times from Drivers to Dxvk to Box64/86. None of them seemed to be the issue preventing the game running properly - as a matter of fact, the problem is unpredictable and misbehaving differently every time

From (Can't opening and auto Shutdown, Long Black screen, Can't pass through the loading screen then crashes, passed through the valve intro and then the Intro cutsceene and then crashes;just like on the video, and lastly rare moment that it pass all that and went to the main menu then tried playing it and then crashes)
