ESP-IDF example for wifi easy connect not working

[sebseb]

Hi,
I followed the instructions below:
https://docs.espressif.com/projects/esp ... t-up-tools

After all is installed, I navigated to the dpp-enrollee folder under wifi easy connect and tried to compile and flash.
All seem well but the output of the esp32s3 that I use shows error:

ESP_ERROR_CHECK failed: esp_err_t 0xffffffff (ESP_FAIL) at 0x420093bc
file: "/IDF/examples/wifi/wifi_easy_connect/dpp-enrollee/main/dpp_enrollee_main.c" line 158
func: dpp_enrollee_init
expression: esp_supp_dpp_init(dpp_enrollee_event_cb)

abort() was called at PC 0x4037be53 on core 0

Please help. Thanks

Hello, I also found the same mistake.
My backtrace is as follows:

My chip worked properly in some previous tests. But after entering the wrong WIFI password one time, all programs that use the WIFI module will report this error. Perhaps it is an error in a register of the chip that cannot be reset? I don't know how to correct this error.
