Looking for WiFiManager.h dependency? Check our library registry!
CLI > platformio lib search "header:WiFiManager.h"
Web > https://registry.platformio.org/search?q=header:WiFiManager.h

#include <WiFiManager.h>
^~~~~~~~~~~~~~~
compilation terminated.
*** [.pio\build\esp32c3\FrameworkArduino\main.cpp.o] Error 1

C:\Users\jaap.pio\libdeps\esp32c3\WiFiManager\WiFiManager.h

fixed it :
/.platformio/packages/framework-arduinoespressif32/cores/esp32/main.cpp:1:10: fatal error: WiFiManager.h: No such file or directory

i deleted folder /framework-arduinoespressif32

Visual studio then installed the folder again
