canon camera not visible in LRC on McBook Pro IOS13.2 with Apple M1

Are you connecting the camera to the computer with a USB cable?  There have been many reports of problems importing and tethering via USB cable with Mac OS 13, mostly with Nikons and Iphones but some with other brands, and though Adobe has issued fixes, there continue to be some reports of problems.

If you're using a card reader, troubleshooting steps:

1. After inserting a card into the reader, verify you can see the contents of the card in Finder.

2. If you can see it in Finder, please post full-resolution screenshots of the entire Finder window and the entire LR window after clicking Import. That could provide important clues.
