Hi. have you tried to set debounce time for the wait_for_edge function?

for example:

// debounce_time set to 10ms
// no timeout
GPIO::wait_for_edge(channel, GPIO::RISING, 10);

If you already set the debounce time, what happens if you increase it? Does it fix your issue?

And could you give us the information of your HW setup? I'm not familiar with HW stuff at all, but somebody else may give you some advice that can fix your issue from the HW aspect.
