I work as a commercial electrician I dont do residential very often so I typically don’t troubleshoot AFCI breakers but I’m trying to help out a friend and anything electrical related I’m interested but I want to do it right with everyone help from this form and the research I’ve done on AFCI breakers I’m confident I’ll find the problem but if I can’t I’m not to proud to say hey buddy your going to have to call a service expert that can troubleshoot this problem for you and get it done right.

Lol nooooo I didn’t call tech support or check no error codes but I have an announcement to make the problem is fix what was the problem I have no idea. I swapped the afci breaker with a different afci breaker in the panel and it solved the problem and never tripped again

That has been my experience every time I've done it, and why I suggested it. One was an incandescent light.

Troubleshooting is a process of elimination. Substitution helps, especially if you don't have to buy new parts.
 
The biggest problem I have found with GFCI/AFCI is the neutral conductors. The dedicated neutral and hot conductors need to be identified from the panel through each junction box to each fixture. A crossed neutral at any point will cause "Phantom" tripping.

Crossing them Causes problems because there not the same circuit. If you crossed two circuits neutral they won't work cause same amount of current is not returning that was leaving the GFCI.

You are correct ! ... What I meant to say ... Don't share that neutral with any other neutrals.
