The problem starts when opening the captive portal in the browser to enter my personal Wifi connection data. My steps to reproduce
restart the NodeMcu and start Serial Monitor (in VS Code): message says "Opened a captive portal", blue LED is on. connect to wifi "Ferraris MQTT": browser opens automatically the 192.168.4.1 with showing the Wifi settings
when the page has loaded, immediately the serial monitor shows an unhandled C++ exception and the whole NodeMcu crashes and restarts: The exception starts like this: Opened a captive portal 192.168.4.1
