Riot Games has temporarily turned off the competitive queue in VALORANT due to an exploit that can disable the flash effect for a player, effectively negating the effects of flash abilities of certain agents.
The flash effect can currently be turned off via a setting in the game’s menu, as numerous players have pointed out over the past day. The competitive queue will remain disabled until the exploit is fixed.
The exploit, which attracted a lot of attention following a video post about it from Sentinels’ VALORANT player Jordan “Zellsis” Montemurro, allows players to completely negate the effects of any flash ability from an ally or enemy. This was done by going to general settings during a match, scrolling down to the Other category, and turning on “Hide User Interface In Game.”
