Hi Esteban,
Can you check if your OneDrive is running in the background process? Just open task manager and look for the onedrive. If it's not there try to start onedrive click WinKey+R then type this %localappdata%\Microsoft\OneDrive\OneDrive.exe
If that doesn't work, try resetting onedrive. Click WinKey+R and type this %localappdata%\Microsoft\OneDrive\onedrive.exe /reset then enter and wait a few minutes until Onedrive restarted.
