I bought Vanguard today, I hit play in Battle.net and it says “Playing now” but game does not launch. I had the same problem with Warzone a few weeks back and I couldnt fix it either.
My laptop can definitly run both, but it’s refusing to.
I found the following reddit post which contains fixes, tried them all but none helped:https://www.reddit.com/r/CODWarzone/comments/mxhurr/pc_i_found_a_fix_to_game_not_launching_playing/
