Why is my seach box not working?

How do you do Sir, here is my question my laptop runs windows10 1909version, after sometime search box in desktop as well as in folders not working let alone working cannot even type, i searched a lot of videos and tried powershell/cmd command reset/resetwindowssearchbox by official itself/from regedit and some more, i tried these things watching tens of videos but none of them worked, is it related to windows itself? In the past it would even though other problems occured, i even it might be from driver but dont know the solution. and one other interesting thing, i installed windows 10 on another device (also acer aspire 3) after updating driver with iobit booster the same problem occured, now i wanna test installing widows11, but not sure. So i wanna know how to solve this problem, thanks in advance
