I have an application that require the power management features. I was using esp-idf 3.1.1, seeing that in 3.1.3 release note there was a "Fixed crash during simultaneous use of Wi-Fi, Bluetooth and modem sleep" I decided to upgrade to this version. However I still have this issue, which will happen every time I successfully join a WiFi access point and seems to be related with the power management since disabling it in menuconfig will work fine. The following is the trace when the ESP32 crashes after having joined an access point:
