Colour selector triggers error on macOS Catalina 10.15.7

(assuming the contract is correct)
When does this happen precisely: a) when right-clicking on a color, b) after right-clicking, when clicking on "Ok" to select the color, or c) after clicking on "Ok" and drawing in the canvas?
Interesting question!
for the other controls to select I left click - right-click does not have a known action if I right click I get the colour picker - it does not select the colour I right clicked (defaults to black) if I left-click I get the error above
in testing this I noticed that mac does not pic up the control-click event that lets you set key bindings (tried ctrl, alt, command keys)

That's weird!

Try to go to Keymap|Buttons|New Shortcut, double-click on the only item (or click+enter), then do a ctrl-left-click in the event listener, click on ok.
Then try ctrl-left-click on a button
it consistently doesn't register the ctrl key.
windows behaves as expected and shows control:left-up instead
Wow, wut?
Can you check "full event", "control", "rcontrol", and try again?
