What hardware are you using? What software, what OS, do you use a VM?

The hardware is ESP32S3-Eye, no VIRTUAL machine is used, and the operating system is Windows. And I tried again later, there was a permission error, I found online that the serial port was occupied, may I ask how I should solve it?

That board uses the internal USB-serial-JTAG converter. You may have firmware loaded in there that is stuck in a bootloop, making it hard to reprogram it. The way around that is to manually put the board into download mode: hold the button labeled 'DOWNLOAD', press and release the button labeled 'RST', release the 'DOWNLOAD button and try uploading the program again.
