Files "disappear" in Files tab; SharePoint link intact

Hello All -

Interesting new issue that appears related (but different) from existing posts related to files disappearing from view.  All the Files tabs in Teams have stopped displaying my files, BUT the link to the corresponding SP doc lib is intact (i.e. when clicking "Open in SharePoint", the doc lib opens and all folders/files are visible).  A few other data points:

- Channel names were not changed

- O365 Group names were not changed

- No change was made to resolve to a different doc lib in SharePoint

Has anyone experienced this?  Known resolution?  Thanks in advance
