ArduSimple WiFi NTRIP Master - cannot set password to hotspot

[djdan7]

I have an ArduSimple RTK2B PRO board along with a WiFi NTRIP Master module. When I try to set a password for a WiFi hotspot, the module crashes. It stops being visible for the wifi connection, 5s reset doesn't work, update frimware also has no effect. Only using the ERASE option in ESP32 DOWNLOAD TOOL and then uploading the firmware helps.

I tested on version 0.52 and 0.54. I tried setting different security options (WPA-PSK, WPA/2-PSK (recomended)), always the effect is the same - the LEDs flash, but you can not connect to the board over wifi (it is not visible).

Greetings!
