Destiny 2 has had its latest big launch, and while many players have been able to enjoy Shadowkeep and New Light after yesterday’s server errors were resolved, it hasn’t all been smooth sailing. Bungie’s tracking plenty of issues across all versions of the game, and there are a handful of solutions you can try ahead of the next patch.
If you’re having a ‘problem reading game content’ error on Steam, Bungie recommends deleting the ‘steam_appid.txt’ file from your Destiny 2 install. That file is typically found under C:Program Files (x86)SteamsteamappscommonDestiny 2, but could also be in the Destiny 2binx64 folder.
If your Steam account has over 300 friends, you might get crashes at the title screen. If so, you need to trim your friends list. For Squirrel or Weasel errors, you should try removing Cyrilic letters from your Steam nickname or clan info. Finally, if you’re having trouble accessing your Battle.net purchases on Steam, Bungie says you should retry the PC migration page.
