You have numerous errors. Let me spell out some of the major ones: You appear to have a XNB mod. Delete it - XNB mods no longer work for SMAPI. Kimchi is already an ingredient in Artisan Valley. Kimchi Maker is a valid content pack but you'll have to rename "Kimchi" into something. I recommend "Kimchee". You have more than one mod that's trying to edit Alex's house - try to find the troublesome mod and remove it. Your biggest problem, though is that you have duplicate files. Go to your Mods folder and delete anything with [PPJA] in the title and check to make sure you don't have any more duplicate folders. I couldn't read the full report but this is a good step. Do another error log if problems persist.
Thank you so much. I thought I had broken something vital updating SMAPI/etc today. I forgot I'd added the kimchi thing last time I was on, but had to run off before I tested it. That was apparently the cause of the approximately 1 billion duplicated items. The rest should be much easier to fix
