I can confirm that downgrading to Zoom Client 5.7.1247 for Windows resolves issues for users. I've downgraded another half dozen users and they are much happier.
We use software deployment software at my office so we have access to previous versions of the Zoom Client. To help others, I checked all over Zoom's website and could not find a download link or page to access previous versions. You may have to contact technical support to get the previous version.
