Same thing happened to me, sooooo annoying! Hit alt-tab and that makes it full screen with audio!
This last update also makes windows ask me every time for permission before the game will start. Everything to do with the game is set to "run as administrator" and I have full privileges to the account.
Then if it finally starts for the first time, sometimes the game plays all jittery with intermittent stalls, and I have to restart it. Every time I restart my computer I have to start Battlefield 2042 twice! Keep in mind I have all nice equipment: i9-12900k, RTX4090, 32GB 6400MHZ RAM, Windows 11, and all the updates to everything. I tried reinstalling everything twice. The game is just so unstable on startup. When it does finally start properly, I'm getting 190 frames per second average on a 49in 5120×1440 Ultrawide monitor at 240 HZ, with everything set to Ultra.
