The issue I had was somewhat different than the messages described in these discussion threads, but since I see the same solutions being unsuccessfully applied to the OneDrive problem. In my case, all files on OneDrive were visible.
When attempting to open any Office files (Word, PowerPoint, Excel, Visio) from my primary laptop computer, the application would start, the file attempted to load or download, then....... nothing. The app launch ended. Office files could not be opened
from within the app, file explorer or anywhere. I could only access the files using the web interface or from the OneDrive app on my iPhone.
I attempted all the solutions listed here; checked permissions, setting trusted locations, deleting office cache, surface scans, resetting OneDrive, and re-installing OneDrive. None of these solutions resolved the issues.
The issues was finally resolved by creating a new user profile on my computer. Once I signed on with the new profile, OneDrive started working again.
Hope this helps!
