Here’re 3 easy and quick solutions you can try to fix this problem. You may not have to try them all; just work your way down the list until you fix your problem.
Solution 1: Turn off the Sticky Keys and the Filter Keys feature

Solution 1: Turn off the Sticky Keys and the Filter Keys feature
Sticky Keys and Filter keys are two accessibility functions in the Windows operating system. Sticky Keys allows you to press one key at a time for keyboard shortcuts; Filter Keys tells the keyboard to ignore your brief or repeated keystrokes. If these two keyboard functions are enabled, sometimes your backspace key cannot work fine.
Follow these steps to turn off these two features to get your backspace to work again:
Window 10
1) Type ease in the search box from Start. Then click Ease of Access keyboard settings.
2) Make sure the status of Sticky Keys and Filter Keys are all set to Off. If you see On, switch to Off.
Windows 11
- Press the Windows logo key and R simultaneously to open Settings.
- Select Accessibility on the left panel, then scroll down the list on the right and click Keyboard under the Interaction section.
- Under the Sticky, Filter, and Toggle keys section, make sure the status of Sticky Keys and Filter Keys are all set to Off. If you see On, switch to Off.
Your backspace key should work now. Check to see if it works. If unfortunately not, please try the next solution.
Solution 2: Reinstall your keyboard
The corrupted connection between your keyboard and your Windows operating system could also make the backspace key stop working. You can reinstall your keyboard to solve it.
Follow these:
1) On your keyboard, press the Windows logo key 
and R at the same time to invoke the Run box.
2) Type devmgmt.msc and press Enter.
3) Right-click on your keyboard software in the Keyboards section. Then click Uninstall device.
4) Reboot your computer; Windows should then reinstall your keyboard automatically. Then check to see if your backspace key works.
Solution 3: Update your keyboard driver
