I have seen similar change of behaviour in Emacs for MaxOSX* which I'm a
dedicated user of, but it happened when I moved from Sierra to Mojave
(IIRC) (note: skipping High Sierra in the path, again IIRC).

I dug real deep into this, and what I found was utterly perplexing. The
codes send by the keyboard hand been swapped right to left, so that
augmenting keys on the left (e.g., Option-Left) was suddenly sending key
codes for the ones on the right (e.g., Option-Right), and vice versa,
which obviously sent Emacs off the rails in a jiffy.

I have sent a bug report about this to Apple, but, alas, I have heard
nothing back.

I wonder if something happened again (going back go normal?) with
Catalina. I haven't tested it yet, so I don't know.

I hope this helps further debugging. You could test, e.g., using the
debugging tool "xev" that will show you the exact X11 events sent to the
app for mouse movements and clicks, and keyboard key presses and
releases, including key symnbols.

                                Best regards,
                                  /Lars-Johan Liman
