@Michael. You don't say what process that you are using to do the import, so it is a bit hard to advise what may be going wrong.
However, if your Win10 is at version 2009, there is a function in Photos to import from Apple or Android devices. After connecting the Ipad to the PC via a USB cable, open Photos and click on Import (top RH corner) then From a USB device. You will see a message on the ipad to the effect that you trust the PC. Click allow on that. The Ipad should be found and you can select what you want to import.
Alternately, if you use File Manager, you should see the ipad listed there and you can browse the DCIM folder and copy and paste your pics from there.
