Please try running the following:

sudo rm /var/run/wpa_supplicant/p2p-dev-wlan0 sudo wpa_cli wps_pbc 

Open Linux Shell, and run below command

$sudo rm /var/run/wpa_supplicant/p2p-dev-wlan0 $sudo wpa_cli wps_pbc 

In my case, this works well.
Of course, sudo wpa_cli wps_pbc is enough to make rpi wps enable, But, sudo rm /var/run/wpa_supplicant/p2p-dev-wlan0 is important for working. I don't know why.

Please check with above shell script
sudo rm /var/run/wpa_supplicant/p2p-dev-wlan0
sudo wpa_cli wps_pbc

Please try running the following:

sudo rm /var/run/wpa_supplicant/p2p-dev-wlan0 sudo wpa_cli wps_pbc
