What's causing "The managed object model version used to open the persistent store is incompatible with the one that was used to create the persistent store." on startup?

I hope someone can give me a clue on what program might causing this message or how to get rid of it. This message started popping up yesterday, and after I click "ok" the computer functions normally (as far as I can tell), but it is really bothersome. It shows up on startup, not when I open any specific app. A logo shows up in the message, I don'y know if ti is a regular Mac OS logo or if it might give a clue to what app in specific is causing it. I am enclosing a screen capture (the message is in spanish as my Mac OS is en spanish, but the actual english language message would be "The managed object model version used to open the persistent store is incompatible with the one that was used to create the persistent store."


It's showing up on both MB Pro's I have:.


MBPro 2017 15"

MacBook Pro (Retina, 13-inch, Late 2013)


Both are running Mac OS High Sierra 10.13.4. I guess it must be some app I installed or updated in the last couple of days, but I'm really clueless. I am enclosing a screen capture of the message.


Thanks in advance for your help.

To potentially track down the culprit, open Activity Monitor and leave it open. Determine if "Chronicle" or something else appears as an open app or process when that prompt appears.
