esp32 can't open COM port when burning

I had this problem when burning esp32, I made sure that the COM port is not occupied by other programs, the driver is up to date and the toolchain is up to date.

You may need to point that to a newer python version (calling 2.7 in example), or you might need to try these steps:

Thank you very much!
