When Battlefield 6 players started sharing screenshots of a blunt system message telling them to “uninstall Valorant,” many assumed it was a joke or a dig at a rival shooter.
But this wasn’t a meme at all. It was an actual launch-blocking prompt from EA’s new anti-cheat system.
The error showed when launching the games side by side, keeping Battlefield from running until the situation was resolved.
What’s Causing Battlefield 6 to Demand a Valorant Uninstall?
The root cause is a clash between two of the most aggressive anti-cheat tools in the industry: EA Javelin, which powers Battlefield 6’s cheat detection, and Riot Vanguard, which protects Valorant.
Both operate at the kernel level, meaning they run deep in the system’s core with maximum access and control. They also depend on Secure Boot, a BIOS/UEFI setting that ensures only trusted software loads at startup.
Because both programs demand exclusive oversight of the system’s protected memory, Javelin refuses to start Battlefield if it detects Vanguard actively running in the background.
In practical terms, this means anyone leaving Valorant open (or even having Vanguard persist in memory after quitting) might be told to remove the game entirely before continuing.
Does This Happen With Other Games?
Players noticed that other titles with similar anti-cheat setups, like Genshin Impact, don’t cause the same launch block.
The difference may come down to how Vanguard is designed to remain active even when Valorant isn’t being played, making it more intrusive to competing anti-cheats than other systems.
Kernel-level anti-cheat has always been divisive. Some view it as the only solution to surpass evolving cheat technology, while others fear it could introduce privacy risks, security holes, and software conflicts.
The Battlefield 6–Valorant clash shows how overlapping systems from different games can end up targeting each other as much as the players.
For now, the issue appears limited to Valorant. Still, it also shows that stronger cheat prevention in competitive games can push players into making choices they never expected, such as which game to keep installed.
