Word accessibility checker stuck on "updating results"

[CaptainReboot]

I have a weird issue with a user and the Check Accessibility feature in Word. It's required that they use it before they send these documents out as they go to various clients. About a month ago, it just stopped working correctly, and gets stuck on "Updating Results"

• New document with text added using Word desktop app - works
• Existing document from SharePoint using Word desktop app - doesn't work. Same document works with the web version of Word
• Save document from SharePoint to local desk using Word desktop app - works
• Opening an Word attachment in email using Word desktop app - works.  Saving same attachment to OneDrive then using Word desktop app - doesn't work.

So the problem appears to be centered around files that get opened on OneDrive/SharePoint and using the Word app.  It works when it's a local file, but the same file that is saved in SharePoint will not work. The web version will work though.  

We are on the monthly enterprise channel, and currently on version 2406, build 16.017726.20206 9x64).

Any ideas?

Good Morning,
Can you confirm your organization does not have connected experiences turned off. If it works local, then it's because the checker is not able to reach online resources.

Thanks for responding. It's enabled.

Thanks..yeah, tried that too. As well as a uninstall/reinstall of the suite. I have a call with MS and I'm sure we'll go through all the steps again. Watch it magically work this time.
