Resetting Save file?

[Ozzman]

My son has a save file he's very fond of, but after trying the Expanded-mod for a while it's no longer playable. The game crashes when he tries to load the save. We removed all the mods and uninstalled SMAPI, but it still won't load. Is there anything we can do to save the savefile?
I found this error-message:

Message: The content file was not found.

Thanks for the log. Yes, SMAPI handles some of the cleanup, but occasionally misses a few things.
We can go in, and edit the save to remove the NPCs, and custom items that cause the crash.

The wiki has some info on this if you'd like to try it yourself. Or if you'd prefer; upload your save here, and I can help with fixing it.

Saves - Stardew Valley Wiki

The game saves progress when the in-game day ends, i.e., when the farmer goes to bed, collapses from exhaustion, or collapses at 2am. All progress during a day is lost if the player quits the game without ending the day. In multiplayer, the game saves after all players click through the prompts...
