As a temporary solution delete /etc/create_ap.conf and re-install the package

Is it regular or occurs time to time? Can you build it from source?

This is also segfaulting for me arch linux under wayland. If I build either the master or lakinduakash-patch-3 branches from source I get the segfault, but when I build lakinduakash-patch-2 from source I get the GUI.

What’s the path of that config file? @awsms

/etc/create_ap.conf I think.

Archlinux’s package manager(pacman) does not automatically merge configuration files, and newer code will get null pointer errors when reading configuration options that don’t exist in older versions.

Wifi interface is blocked due to iw is not installed. Please check all the dependencies before installation.
