Do'nt work interup in ARDUINO

[bravehamid]

Hi, I hope your time is fine
I wrote my program with Interopet, but for the first time, no matter how much the second key (one of the interopts) is, I will not work until I turn the first key (to another interpolate patch) to start it completely, and then it works well too. What does it mean to you?
I wrote with PCINT

This works for me.

Show your code.

Show your circuit.

What doesn't work ?

INTx pins are used for external interrupts.
