Someone in the forums has found the error, the post I can not find now, but Javelin is not communicating with Battlefield 6's license/entitlement. Meaning that Javelin can not verify that the game is legit. Apparently from what I can see in the forums this is affecting all different kinds of variations of PCs. This is why none of the fixes have worked for this. Secure boot, boot drive configuration, changing security properties, etc. The anti-cheat is the current problem, I found a post earlier and just reposted my own take. EA as far as I know does not care about this issue.
