A bug in Call of Duty: Warzone is preventing the game from launching through the Battle.net launcher on PC, developer Raven Software confirmed Thursday.
"We're investigating an issue preventing players from launching #Warzone via the PC Battle.net client," the studio wrote on Twitter. "In some cases, we're noticing conflicts with anti-virus software."
The studio did not name a particular anti-virus program causing the problem, but said it would share more info about the bug and its resolution as they information became clear.
It's unclear how widespread the bug is, but its severity likely warrants immediate attention from Raven.
Raven released a Warzone patch earlier this week to fix one bug that allowed players to get out of bounds on the new, '80s-themed version of Verdansk, and another that prevented players from completing the new Hunt for Adler limited-time event.
