Sometimes First Stage Bootloader keeps resetting for TG0WDT_SYS_RST and esp-idf application is not started

ESP_IDF: v4.4.6
Chip: esp32s3-wroom1 n8r2

In our custom boards we are in production with, we found two samples with a strange behaviour:

when the board is powered on, sometimes the app start normally while sometimes it get stuck in the first stage bootloader and keeps resetting for TG0WDT_SYS_RST and after a few times also for RTCWDT_RTC_RST.

Anyone knows how to solve the problem?
