Required to lock TCPIP core functionality!

[RoelHermus]

The installing the latest 3.1.0 version of ESP32 by ESpressif System continuously restarts the esp32 with the error:

assert failed: tcp_alloc /IDF/components/lwip/lwip/src/core/tcp.c:1851 (required to lock the TCPIP core functionality!)

After reinstalling version 3.0.7, the problem was solved.

will be fixed/updated to work with core 3.1.0

@lbernstone Thank you for pointing this out. I reviewed the ESPAsyncWebServer repository, and it seems the issue is indeed related to the "Required to lock TCPIP core functionality!"

Same issue with esp32, @me-no-dev Kindly look into this issue.

confirming I am also getting the same "Required to lock TCPIP" issue on an ESP32-WROOM-32D. Downgrading to the previous version of esp32 by espressif also solved the problem for me.

@sh0rtrange Thank you! I'll try that as a temporary workaround. I really appreciate your input!
