Many players encounter the dreaded “Infernal Error” when launching or playing Diablo II: Resurrected on PC. This error often crashes the game, closes the launcher, or prevents login entirely — especially in Battle.net multiplayer.
Typically, the issue stems from network interruptions, corrupted game files, antivirus interference, or outdated drivers. Fortunately, the solutions below fix the problem in most situations.
