LrC can't tether to Canon R5 or R3 camera

[defaultnxbaqtoqmuhl]

LrC 14.3 doesn't find either of my cameras when attempting to tether.

Apple M3 Max with MacOS 15.3.1, LrC 14.3, Canon R5 Firmware 2.1.0.

Computer/cable/camera works for both cameras using the Canon EOS Utility 3.

I tried all of the ideas presented in the Adobe document https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-tethered-capture-lightroom.html  but that didn't help.

Another post sugested removing a Nikon Plugin, but I didn't have that plugin.

Seems to be a LrC problem. Would love to be able to tether directly to LrC instead of using EOS Utility.

Any other ideas?

I just tested an R5 with Firmware Version 2..1.0 on a Mac M1 (macOS version 13.5.1) using Lightroom Classic 14.2  and the R5 connected in under 1 second after hitting the [OK] button. 

The likeliest cause is mis-configured permissions for Lightroom Classic in the Mac OS.
