I knew the second I posted this, the cause would become clear. 🙄
I realized that my class instantiation was wrapped in an is_admin condition. Hence the options page worked but I couldn’t get my data! I’m kicking myself.
I have the same error on my post editor, media library, widgets editor, and user editor pages. We are not using The Events Calendar, but here’s a list of our plugins:

@elliot: I am using the latest ACF Pro. I can say that I’d never seen that happen before, so perhaps it was a fluke. The site is an active development project, so any number of things might have borked it. If I ever see it again, I’ll try to gather more data. Thanks!
Thank you! I had to change that meta value to a:0:{}. Emptying it completely resulted in all my fields disappearing!
