What happened?

i have an ESP32-T3 with WebSerial library which uses the latest ESP Async TCP and latest ESP AsyncWebServer. Esp32 boards version is 3.3.0. The software which i have written to show some data on a webpage is crashing with the following error:

Assert failed: tcp_alloc, tcp.c:1854 (Required to lock TCPIP core funcitonality)

Stack Trace

Minimal Reproductible Example (MRE)

Run WebSerial example on a ESP32-T3:

I confirm that:

• I have read the documentation.
• I have searched for similar discussions.
• I have searched for similar issues.
• I have looked at the examples.
• I have upgraded to the lasted version of ESPAsyncWebServer (and AsyncTCP for ESP32).
