This is a problem with the Windows Update not updating the applications properly. I recommend checking the system for errors using Command Prompt (run as Administrator) followed by
sfc /scannow. This process might take a while, and it's recommended to avoid using the computer while it finishes the procedure.
Retry update, and if you still encounter the issue, use the Media Creation Tool to manually update to Windows 10.
