After updating to Windows version 2004 Touch screen no longer functional

After updating to Windows version 2004 Touch screen is no longer functional. Tried uninstalling update to return to previous version, but touch screen is still not functional. Performed a Reset of Windows and installed Windows clean, the touchscreen is still not working. In settings it says there is no touchscreen or pen drive available. I’d like to reinstall device drivers for the touchscreen, where can I find device drivers to download?
