How do I get my PC to display my iPhone XR in File Explorer?

I plug in my iPhone via USB. The phone asks if I want to trust the computer. I click "Trust". The iPhone connects to iTunes on my PC. The PC dings like it normally would when you connect a USB device. However, nothing appears in 'This PC'. I spent 90 minutes on the phone with Apple Support. We did an ARA session which allows them to view my PC screen. The tech had to give up.

I have the most current drivers installed on the PC.

We don't know what "PC" and if compatible with iPhone XR transfer. What setup of iTunes have you done on the PC? Like this for Windows?
Like this for Mac OS?
Like this for Chrome?
How about Linux? https://beebom.com/how-use-iphone-with-linux/

When I've had problems similar to this I've had to completely uninstall anything from "Apple Corporation" from my PC and then reinstall iTunes again. Once this was done I was able to connect.

It's a pain since there are 8-10 things to uninstall with a few reboots in between before you can re-install.
