ESP8266 ESPAsyncTCP Error

Hi, suport highly appreciated !!
Using Arduino IDE I tried several standard codes with included ESPAsyncTCP.h library( e.g. ESP8266 NodeMCU Web Server with Slider: Control LED Brightness (PWM) | Random Nerd Tutorials ) without any changes and with all of them I got following (or similar) error message :

Arduino: 1.8.13 (Windows 10), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, 115200, 4M (3M SPIFFS)"

Fehler beim Kompilieren für das Board NodeMCU 1.0 (ESP-12E Module).

I checked the library folder, I tried several versions of the library, I tried several examples, always error messages with reference to ESPAsyncTCP.h

Thanks for help !

If your ESP8266 core is about as ancient as your IDE version that might explain the problems. I don't have an ancient core of the ESP8266, a current version does provide the std::nothrow functionality.

Thanks a lot, I loaded IDE V 2.1, but the same problem occurs. I’m wondering because the ESPAsyncTCP library is 4 years old. How to update ESP8266 core?
Best regards

Thanks a lot, after upgrade to ESP8266 core 3.1.2 it worked..
Best regards Hans
