Hello, this is Emily.
Shift + Delete does permanently delete the files by bypassing recycle bin. From Windows' perspective, it is doing what it is supposed to do, so there's no way you can recover using any of Windows' native feature.
You might be able to, while no guarantee, to use third party tool to recover. I will be completely honest with you, even though you may not like to hear this, a good recovery tool is not really free. They can be free for you to see the files, but by the time you need to recover it, it will require payment.
Here is another fact that's important to you. When files are deleted, it is important that you want to do as little as possible on the drive to increase your successful chance of recovery. If the files are important to you, you wouldn't want to try different free ones, as during tose processes, you can be also losing your chance to recover successfully.
Recuva is usually a tool that's often recommended.. but I believe it is only free to review the files but not free to actually recover.
