Unable to import from phone to LRC. "Files were not imported because they coudl not be read or..."

I'm stuck trying to import photos off of my phone. I previously ran into the same issue but was too busy to chase this frustrating block and ignored it until now I've run out of space on my phone and have no choice but to fix it. I'm running Lightroom Classic 2022-v12 on Windows 10.

When I import, the progress bar appears and never moves. When I cancel it, it alerts me that it has already given up and simply chose not to tell me (bad design). The error message, of course, is this:

"The following files were not imported because they could not be read or the destination folder is not writable. (3912)"

To be clear, I've read through about a dozen full threads listing endless fixes for this and tried my best to do as many recommendations as possible without any luck. People seem to repeatedly recommend fixing preferences, but as far as I can tell I've done that.

So far, I've tried all of the following and have not found a way to consistently import.

• Restarting Lightroom.
• Restarting the computer.
• Plugging my phone into different USB ports.
• Using 3x different USB cables.
• Keeping phone screen active during import. Allowing permissions.
• Running Lightroom as administrator.
• Enabling full control (includes "write") permissions to all users for the exact import folder, its parent folder, and then for the top-level drive folder.
• Importing to each of my four drives.
• Importing to Users, Users/ME, and Users/Public.
• Disabling "Make a Second Copy To" option in import dialog (it was already off).
• Lightroom had already updated to the latest and updated its catalog with it.
• Reset Lightroom's preferences.
• Importing just one photo (to confirm it's not being overwhelmed).
• Importing a different photo (to make sure that specific one wasn't corrupt).

I've somehow managed to import about thirty out of the thousands of photos I've got backlogged but there was no clear pattern or explanation. I've also imported a full set of images from a different camera with a card reader. These would seem to rule out both PC hardware and drive permissions.

What can I do at this point to get my photos into Lightroom?
