BF6 crashes after install Win11 2026-09 Preview Update (KB5124010) (26300.9539)

same happening to me right after re-starting the computer whilst the newest Win update KB5124010 was installed, right after that the game launches while in background and when I moveover the cursor to it and enter (clicking in) the game instantly crashes to the desktop without any error msg. I'm not using steam but launches via EA app, so it's not limited by steam but the game respective Javelin entirely. 
I'm gonna reroll the windows update now and hope everything return to back normal. 
yday w/o the win update I could play completely issue-free 

I'm using the EA app. Battlefield 6 and F1 2025 crash to the desktop after a minute. It's the Javelin Anti-Cheat's fault.

Thanks... I had the same issue. I had tried all of the usual things, but had no luck. I uninstalled "Preview Update (KB5124010) (26300.9539)", and viola, the game runs again.

i think since javelin is working on kernel level it needs some time for them to build it for a specific release.

Thats fair, just its the first time for a while a game hasn't worked for me on release preview and I don't typically try to use the beta, canary or experimental builds on real hardware or for any day to day use.

So this is actually a preview build of what will be released to non-insiders next month so hopefully will be resolved by then.

AFAIK Preview Updates are simply not supported. Like the rest of BF6 it is a hit and miss. 

I am having the same issue.

It was working perfectly fine with

26300.9445
26200.9267
26200.9168

And well any update prior to that.

Considering 26300.9539 had every single change as a gradual update it was annoying, but glad someone else is having the same issue so it means I am not alone.

For info, I can see that EA Anticheat is crashing out in both the application and system logs and reinstalling EA Anticheat hasnt helped one bit. 

Hopefully something is done before the 13th October when windows update for non-insders will get newer (albeit 26200) builds.
