Fix for Steam Crash

[BoNGIIDuNGII]

I found out that the issue most likely stems from having used tools like Summoners War Exporter or Rune Optimizer in the past. Personally, I’m not a big fan of downloading extra programs just to fix problems, but that’s entirely up to you.

If you can find a way to completely uninstall Summoners War from your PC—meaning absolutely everything related to it, including leftover files or unused programs that might still be causing issues—that might help. In my case, the only thing that worked was using Revo Uninstaller. I did a full cleanup and deleted everything associated with the game. After that, I reinstalled it and it worked perfectly right away.

That was the only method that worked for me. No matter what I tried before, nothing else solved the problem. So, best of luck!
