Examples not compilate for ESP32 on ArduinoIDE 2.3

[MarksRU]

Describe the bug
When compiling any example from the library for any ESP32 module, I get an error.
The compilation for ESP8266 is successful, the example is loaded into the module and works.

При попытке скомпилировать любой пример из библиотеки в среде ArduinoIDE 2.3 для модуля ESP32 получаю ошибку.
Компиляция для ESP8266 проходит успешно, пример загружается в модуль и работает.

I just built all of the examples for Arduino IDE 2.3 and did not have any errors.
