The error means SMAPI can’t find its own core files (SMAPI.Toolkit.CoreInterfaces.dll) or the correct game path. This usually happens if SMAPI wasn’t installed properly or files are missing.
How to fix:
1. Uninstall SMAPI completely (delete Mods and smapi-internal from your Stardew Valley folder).
2. Reinstall the latest version of SMAPI from smapi.io.
3. Make sure you select the correct Stardew Valley install folder during installation.
4. Verify Stardew Valley’s game files in Steam.
5. Ensure .NET Desktop Runtime is up to date on Windows.
After reinstalling, SMAPI should launch correctly again.
