While compiling, I am getting the following error:

In file included from c:\Users\marce\Documents\arduino\libraries\TFT_eSPI\TFT_eSPI.cpp:24:
c:\Users\marce\Documents\arduino\libraries\TFT_eSPI\Processors/TFT_eSPI_ESP32.c: In member function ‘uint8_t TFT_eSPI::readByte()’:
c:\Users\marce\Documents\arduino\libraries\TFT_eSPI\Processors/TFT_eSPI_ESP32.c:113:9: error: ‘gpio_input_get’ was not declared in this scope; did you mean ‘gpio_num_t’?
113 | reg = gpio_input_get(); // Read three times to allow for bus access time
| ^~~~~~~~~~~~~~
| gpio_num_t
exit status 1
Compilation error: exit status 1

What I have already double checked:

  •  TFT_eSPI version is 2.5.43
  • the file User_Setup.h (the correct one with 19KB) is on folder  C:\Users\marce\Documents\arduino\libraries\TFT_eSPI
  • LVGL is V9.3.0
  • lv_conf.h is on folder C:\Users\marce\Documents\arduino\libraries

Does anyone knows how to solve it?

The issue was solved by uninstalling TFT-eSPI V2.5.43 and installing again the same version (2.5.43)
I do not why, but now is compiling OK
