The resume button only works once when I debug.

I'm trying to collect values through debugging using the Resume button, but it only works once. What could be wrong?

What does "not working" look like here? Does the connection drop? Does "Stop" still work?

Low power states and unexpected resets can mess with things. Should work apart from that.

Crystal issue, low power mode caused problems to me before. Hardware failure interrupts. Try to lower your connection speed and enable low-power debugging or change whatever about it
