Hi Brandon G, I can see how frustrating it must be to run into a bug like this especially when something as simple as renaming a file ends up breaking it.
To avoid file corruption in the OneDrive Android app do not rename files using the app until Microsoft releases a fix instead use the OneDrive web version on your PC or Chromebook or the desktop app on Windows or macOS to manage files safely renaming files through onedrive live com works without issue and is the safest workaround for now you can also report the bug by opening the OneDrive app tapping your profile selecting Help and Feedback and choosing Report a Problem some users have had partial success by clearing the app’s cache and storage through Android settings then reinstalling the app from the Play Store finally monitor Microsoft’s support page for updates or hotfixes related to this issue.
When you rename a file in the app and it becomes corrupted or duplicated. does this happen immediately or only after the app syncs with the cloud or refreshes?
Best regards
