Sorry, the issue was in hw. One of the diodes on the relay coils was soldered in the opposite way and was shorting the PSU when the GPIO is high. I didn't see that in first place because the device is consisted of 3 PCBs and this particular component wasn't visible without desoldering the PCBs

Re: Are there any tools to help debug watchdog timeouts
I am experiencing a similar issue but in my case esp_timer is the currently running task. The funny thing is that I am not using esp_timer in my code and it must be some of libs my code depends on. I have spent over a month trying to debug this issue but without any success. With some changes in my ...
