Hi,
There is no major update released last year, hence the Go back function isn't working. Please try this:
Please open the Windows Recovery environment using the steps below:
Open Settings App by pressing the Win+I keys.
Navigate to System> Recovery menu.
Click Restart Now button beside Advanced Startup.
Choose Troubleshoot menu.
Select Uninstall Updates > Uninstall Latest quality update/Uninstall Latest Cumulative update.
Let the process complete.
Hope that helps, and rely on us for any further inquiries. All the best.
