Symptoms

BattlEye fails to decrypt packets

Reproduction

Install the game using lutris and add an environment variable for the location of the Protin BattleEye Runtime. Eg. PROTON_BATTLEYE_RUNTIME=/Games/Steam/steamapps/common/Proton BattlEye Runtime/

The game will launch OK and will fully work in offline mode - however, if you try to connect to an online game, almost everything loads just fine, but at the last part of the connection it fails with the following message in the console:-

[Exception] : IndexOutOfRangeException: Index was outside the bounds of the array.

Start by reviewing the compatibility report and reproducing the online connection failure with Proton 6.3, Lutris, and the specified Proton BattlEye Runtime environment variable. Compare the BattlEye decryption exception and system information with current Proton and BattlEye support; done would mean the game connects to an online match without the packet decryption failure.
