B4R Question esp32 ap server scan networks stack crash

trying to add a little web interface for setting ssid and passing password through post method. I receive a crash of module occasionally. It does work sometimes but crashes most times. It will actually reboot program. It will work fine if I remove the HTML code and just send ssid as text. Not sure if I can increase the stack size.
the log reads this during crash:
