Can putting frozen food in a hot ceramic pan cause a thermal shock?
I'm gonna risk getting chastised and answer from first principles, rather than any referenced sources!
The pan will not be affected at all from this.  A home freezer will chill foods down to around -20C, a refrigerator to around 5C and the stovetop can heat your pan up to around 350C.  Putting food from the fridge into your preheated pan (its most common use-case) could expose the pan to a mass 345C cooler than it, from the freezer 370C.  The temperature differential between the two cases is really not that different (~10%) and well within the ability of any pan to withstand.  If it were possible to damage a pan with such a small variation from its most common use case, it would also be just as likely that a more efficient/higher temperature stovetop would also damage it.
In short, the only pan that would be damaged by this would be a pan that was not fit for purpose.
