Troubleshooting Guide: "Could not initialize Steamworks API" Error in Oneshot

3. The File Integrity Trinity

• For Steam games: Right-click the game in your library > Properties > Installed Files > Verify integrity of game files.
• For Non-Steam/Modded games: Navigate to the game’s root folder. Look for steam_api.dll (32-bit) or steam_api64.dll (64-bit). Delete them, then reinstall the game or the mod framework (e.g., MelonLoader, BepInEx).

Conclusion

Match User Permissions: Ensure both Steam and OneShot are running under the same user context. If you run one as an Administrator, you must run the other as an Administrator as well, though it is generally best to run both with standard permissions. could not initialize steamworks api oneshot
