The client crashes with "Error_game_crash", often at startup or while playing.

Also appears as: Error_game_crash, error game crash runescape, runescape Error_game_crash, runescape client crashes at startup, runescape corrupted cache

Jagex's support article says the problem is likely caused by corrupted files in your Jagex cache, and tells you to clear your cache files. If it crashes while you are playing, it points to its connectivity troubleshooting steps. Jagex's Clear cache article says to wait for the progress bar under the lobby to reach 100% before playing again. Both articles are tagged for RuneScape and Old School RuneScape.

Fix it, step by step

  1. Clear your Jagex cache

    Clear your Jagex cache. On Windows, while the client is loading click the Options cog in the lower left, find the Cache folder and delete the whole folder. Jagex's Clear cache article also lists typing the command deletejs5caches into the Developer Console and restarting the game.

  2. Clear the cache on Steam or Mac by deleting the RuneScape folder

    On Steam, right-click RuneScape in your library, open Properties and the Local Files tab, and delete the RuneScape folder. On Mac, search Spotlight for your Jagex folder inside your user folder and delete the RuneScape folder inside it. Both are from Jagex's Clear cache article.

  3. Wait for the cache progress bar to reach 100% after clearing

    After clearing, start the game and wait for the cache progress bar under the lobby to reach 100% before playing. Jagex says the client downloads fresh copies of the files.

  4. Try Jagex's connectivity steps if it crashes during play

    If it crashes while you are playing rather than at startup, Jagex points to its connectivity troubleshooting steps.
