Microsoft Office SDX helper- High CPU in background

Today while I was doing work my computer fans started whirring for seemingly no reason- all I had open was google chrome. I checked task manager and found on program, Microsoft Office SDX helper, was using large (as in 70%) CPU out of the blue. Worried that it would crash my computer, I hit end process and nothing happened, so I thought I had solved the problem. However, this evening went I went to do more work the same issue happened, and again SDX was the culprit. And now it just happened a third time.

I can't imagine what is causing it to do this. I had not opened any office programs since I last restarted the computer and it has not happened before today. For a short term fix, I uninstalled Office for my sanity and not needing to keep the task manager tab open all day. Does anyone know of this problem/how to fix this?

Moved from: Office/ Unknown/other / Windows other / Office 365 Home
