The USB cannot be recognized by the PC as some functions are incorrectlly called.
How to solve
Press and hold BOOT, click RST, and then release the BOOT button to burn.
Principle
During the initialization process, ESP32 undertakes a verification of the voltage level on the BOOT (IO9) pin. If the voltage level is determined to be high, the system proceeds with a normal startup. In contrast, if the voltage level is deemed to be low, the device enters into the programming mode. By default, the BOOT pin maintains a high voltage level, but it transitions to a low level when a button is pressed.
