MarlboroRed2000 I noticed that downloads are not listed in the sidebar
Is it possible you deleted the folders? If you look in either the stock files folder or another file manager, do you see folders for Downloads and Documents?
MarlboroRed2000 Can't be that in this case only a recovery is an option
You can try clearing the app's storage in Settings > Apps > All apps > Files > Storage and cache to see if that helps.
