Issue Repetitive error whenever I try to sleep for the night

[Brly31415]

Oddly just now, SMAPI registers this error message repeatedly just as I sleep to save the game. It was running fine before, then I tried to sleep and the screen turned black and didn't change and when I checked SMAPI, this error message kept popping up. Updating SMAPI and all other mods I could didn't help. Though I recall a while ago accidentally adopting a child that didn't appear, nor did it start spousal dialogue about adopting.

Error Log: https://smapi.io/log/293f9b8405c64892a7c4f7c4bc15474c

Any help would be greatly appreciated!
