Please try this first by running the hostapd on foreground and with
debug enabled (replace "-B" with "-dd"). This should provide more
details on what failed.

Are you sure it was "wlanap" and not "wlan0ap"? It would likely be the
interface used for management frames.

wifi0 is not used with IP/bridging configuration. wlan0 is used for more
