So, I am unsure if they have released a patch in the last couple of days to sort this but I'm sure people will come back to me with a response.
I just downloaded and installed Batman Arkham Asylum to play through again and realised I didn't have the .NET 3.5 Framework installed (Subsequently 3.0 and 2.5 but I doubt this would affect it). I also needed to setup DirectX from the games redist folder for the game to run properly.
After doing these two things I was able to load into BF6 after a small 2-3 second hang on a Black window where previously I would only get a black window which would hang and then close after a few minutes, Much like others have been plagued by.
So double check you have .NET 3.5 Framework installed by following this video:

If it isn't installed then grab it here:

I hope this helps others but I can't guarantee it will.
with a new installed NET3.5 and the new "update" of BF6 my pc shuts down immediately after starting the game. it doesnt even gets into the menu anymore
