This document might be particularly helpful, specifically the note about Zigbee bulbs at the end. April can tell you all about Cree bulbs, but I'm pretty sure the GE bulbs are also high on the same "naughty list." There isn't a good solution here besides replacing the bulbs or keeping them on a separate network (a Hue Bridge or second Hubitat are two things that would work, though with the Cree bulbs I still had bad luck with the second Hubitat--Hue works great). If the cause, this would only explain the Zigbee device issues, but it's definitely worth knowing.
