Almost certainly the same problem - and you have it dangerously wrong.

You must BOIL ripe red kidney beans (and, presumably, all Phaseolus
beans, including runners) for at least 5 minutes (preferably 10) to
destroy the toxin. It is unaffected by soaking, or slow cooking at
low temperatures. Most of the toxin is in the skin.
