Pathlight disappeared from app and will not reconnect

I have 12 Ring battery powered pathlights. While replacing batteries today, I noticed that one of my lights was not showing in the app at all. I replaced the batteries and tried to pair it with my system. Everytime I get the the calibration step in the app, the app crashes. I have tried switching the batteries again, logging out and back into the app, restarting my phone, uninstalling and reinstalling the app. Same issue. Any thoughts on how to pait the rogue light?
