"You have been denied permission to access this folder" Windows 10 Error when trying to access files on a mobile device

Device Type: Mobile

Model: BLU Grand XL LTE

Android Version: 7.0

OS: Windows 10 Pro

A family member ended up smashing her phone screen and wants me to transfer her photos to my old phone so she can use it temporarily. However, once I connect the phone to my computer through the USB, it presents me with an error "You don't currently have permission to access this folder." Clicking "Continue" leads me to another error "You have been denied permission to access this folder." I've done research on how to fix this error but each solution requires entering the "Security" tab within the Properties. However, it doesn't give me that tab for the device. If anything, I'll log her into both phones through her Gmail and try to sync the photos from her phone to mine. But for future reference in case I need to transfer any documents between them, is there any way I can bypass this error to access the phone's files? There's no password on the phone and file transfers previously worked before now
