Hello,
Since the August 26, 2025 update, Overwatch 2 has been systematically crashing mid-game with an EXCEPTION_ACCESS_VIOLATION error. The game was working perfectly before this update. No hardware or software changes have been made on my end since then.

I’ve done absolutely everything possible: uninstalling/reinstalling/repairing the game. I’ve spent almost 8 hours checking my BIOS, processor, updating my graphics card, drivers, etc. Everything is clean. I’ve tried launching several games that use different graphics engines, such as Fallout 4, Rimworld, Silent Hill 2 Remake, etc. I haven’t encountered any issues or crashes, even during very long sessions and with multiple games running at the same time. I play Overwatch a lot, about 5 nights a week, sometimes lasting up to 4/5 hours non-stop, if not more, and I have no problems. I played again very early Monday morning for several hours. Tuesday you did the update, I couldn’t play Tuesday due to lack of time, last night at midnight I launched the game and it crashed every time I started a game, even though I had absolutely nothing changed on my PC or installed anything between Monday morning and last night (Wednesday evening 08/27).
