Battlefield 6 Randomly Closing (now won't even open)

As the title says. I've been playing BF6 since launch everyday without any issues. As of the last two days I now have a problem where the game just closes. It doesn't crash or freeze up it just closes without any warning.

At first I was given the error "EA Javelin Anticheat has detected an unacceptable configuration" error message. I have no idea why this happened but since then I have completely reinstalled EA Javelin, including a lot of other fixes related to the program. Clearing the cache etc.
I have done a complete reinstall of the game
I have done a complete reinstall of Javelin
I have verified the game files via Steam
I have also made the game run in -DX11 via Steam, in case DX12 was the issue.
I have disabled Steam/Discord/GeForce overlays.
I have ran the game as administrator.
I have disabled all Antivirus.
I have ran the game in performance mode via windows
I have read that GeForce enabling "smooth motion" can also cause crashes, I have disabled this also.

I am lost with what to do now. It STILL doesn't work... But it's been absolutely fine up until now.
I am of course not hacking and haven't changed anything in my configuration files, so it's odd Javelin ever gave me that message. I can sometimes boot up BF6 and get a game or two if I'm lucky, though 90% of the time it now won't even open and there are 0 error messages.

Is there anything else I can try?
