Thanks for the log.
Yea, so I helped another user with a similar error over here:
https://forums.stardewvalley.net/threads/move-furniture-then-game-crashed.18347/
I've been investigating further, and now with your log.
I will look into reporting the bug now that I can confirm that it appears to be a CF pack agnostic, issue.

Overall, I'm like 99% sure that's the core issue for you.
So, to fix your issue, we'll have to delete the furniture item from your save, and you'll have to temporarily stop using this CF mod.

Find your saves:
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...

I don't know if SpaceCore has any other modded items saved in the
spacecore-serialization.json
file.
So, I'd recommend uploading your save folder here so I can safely check what needs to be deleted, or if the whole file is safe to delete.
And, remove that CF mod so it doesn't break the save again.
