Howdy, thanks for the log!
So, there's a small error with Mumps; claiming a conflict with PyTK. You can try removing PyTK. It's a long mod list, but you seem to have some of the updated versions of mods; like TMXL for example which no longer need PyTK.
But, your main issue is "BFAV Squirrels". There's already a bug report/fix by a user named Renesh on the mod page: https://www.nexusmods.com/stardewvalley/mods/4051?tab=bugs
Check out their fix, and it should let you progress to the next day.

Forgot to add. CustomFurniture/SpaceCore is having some issues lately with how it loads CF items.
And, there's potential for crashes. I'm not seeing any errors for that in your log; so this is just an FYI.
But, it's recommended to temporarily remove those mods. The error looks sort of like this: "The given key '66' was not present in the dictionary."
The number will change, but it has that basic error; and references furniture.
Fixable, but I've been seeing a lot of users with it lately.
