A Microsoft file hosting and synchronization service.
This could be a OneDrive client issue, although a regression isn’t confirmed.
I’d try Settings >> Apps >> Installed apps >> Microsoft OneDrive >> Uninstall, restart, then reinstall: https://support.microsoft.com/en-us/onedrive/reinstall-onedrive
Keep your existing folders and select D:\ODTest during setup.
If it still fails, did this D: location work before the update? Let me know, and I’ll follow up.
