Sonoma 14 Mac book constant fan and overheating

I updated my MacBook to Sonoma 14 a few days ago. Since that time the fan runs constantly even when nothing is open. The battery obviously dies much faster. In the activity monitor it says CMFSyncagent is 92.3% and remains at the top of the list far exceeding any other activity. I did the whole shut down, hold option/shift etc for 7 seconds thing. Once restarted this stops the fan for about 5 minutes. I don't have many downloads on my Mac. I have a ton of storage. I am blaming this on the update and not sure how to correct it.

MacBook Pro (2017 – 2020)

Why Apple doesn't test this software on current systems beforehand is unreal. My Mac is so hot, it will burn your skin. I can't imagine how much life I'm losing from my Mac due to the heat this update is causing. If I was conspiracy theorist, I'd bet that is their goal.....sell more computers. They could easily fix this but they don't. I dare Apple to provide a reasonable answer.
