Hi Justin, Welcome in Community

Thank you for the details, because no upload errors are explicitly logged, this deadlock is typically tied to localized user profile corruption, credential isolation, or deep-level folder permission flags

We need to start in little steps:

1. Open Terminal (PowerShell) or Command Prompt as Administrator.
2. Run the following command (replace the path with your actual OneDrive root folder path if it's not the default):

icacls "%USERPROFILE%\OneDrive" /grant %username%:(OI)(CI)F /T /C

This forces absolute full control permissions (F) recursively across all directories (OI/CI) even if a specific file is locked

Then, press Win + R, paste the following path, and hit Enter:

%localappdata%\Microsoft\OneDrive\settings

1. Delete the PreSignInSettingsConfig.json file if present.
2. Next, open the Windows Settings App (do not use the GUI directly yet). Search for "Settings" in the Start menu, right-click it, and select App settings.
3. Scroll down to the Reset section and click Reset.
4. Reboot your machine, open OneDrive, and re-authenticate

Let me know how it goes
