Do you have other APs on WLC without having this issue?
I would check the correct country code configured on WLC that match -D regulatory domain

IMPORTANT: On IOS-XE, Cisco do not recommend CDP and LLDP to be both enabled (CSCvr24032).
Is the AP connected to port Gi1/0/44 powering up or not?
WARNING: Pay close attention to CSCvv54912.

AP connected on gi1/0/44 is up and registered in wlc.
Only issue the operational status is down

I think I know what this is.
If you reboot switch 1, does the issue go away?

Will check rebooting the switch and post the update.
Thanks Leo laohoo
