AFCI - Breaker keeps tripping.

Have a AFCI breaker that keeps tripping. Not the breaker, swapped wires to a different breaker and same issue. Started off with tripping every few days and now it will not stay powered on.
After pulling the wires on what I assumed was the middle of the circuit the trips became better, basically took a minute to trip rather than tripping right away.
Does anyone have recs on how to find the issue or is pulling each receptacle, one by one, the only solution? All the outlets were empty and light switches turned off.

You probably have a staple that’s stapled too hard. You can always just put a regular breaker in there. Not saying I suggest that but I don’t think it would hurt anything.

Have you hung any pictures or done anything else that penetrated the walls where the circuit runs that could have clipped one of the wires?
What is the brand of AFCI breaker? I know the ones that our builder installed are Eaton AFCIs, and each breaker has a small red light on it that will blink when it trips. The sequence of blinks tells you why it tripped. I would think you would know if yours had this feature though.

Fixed this issue last week for a client. GFCI outlet (one of three) in the garage would stay tripped. Nothing wrong with the outlet at all, turned out to be the fault of a lazy contractor and electrician who had installed a seperate circuit for a backyard water feature. The pump was originally plugged into an extension cord that was direct buried then plugged into an exterior outlet. They just cut the extension cord and left it buried and plugged in when they ran the new circuit, when enough rain had saturated the ground it started tripping. If you've had any recent work done then it's possible to have had a line damaged. I've also seen the same with exterior outlets in decks and patios where the seal had deteriorated with age and would just let water in until corrosion became the issue. Unfortunately without specific test equipment that's generally beyond what even a dedicated DIYer would invest in, it's hard to trace live wire faults inside of walls, attics, etc.

Make sure nothing is plugged into the circuit and make sure the breaker is off.
Use an ohm meter to check for a short by touching the leads to the black wire and white wire. Then black to ground. Then white to ground.
If there is a short. Start unhooking wires from each outlet, switch, light, etc. And then check for the short using the same method.
This well help you figure out what stretch of wire your short is in.
Now if you dont find a short with the ohm meter, theres a possibility its arching somewhere. That's a little hard to find.
In that case, you can start with leaving the outlet, switch, whatever the the line runs to first connected. Then unhooking the rest of the circuit that feeds the other outlets, etc.
Cut the power on and see if it trips. If it doesnt, the. You know that stretch is good.
Then go to the next outlet etc and do the same thing. Keep working down the line until it trips. That well help you locate the stretch were it may be arching.

Best thing to do is get rid of that arc fault breaker and install a normal one. They are required to pass code but after that I would get rid of them as you start having problems with them. If it is a true fault on the circuit it will trip a normal breaker also
