Q: An error appears: 'dfu-util: No DFU capable USB device available'

This issue occurs because the ESP32-S3-Nano is not recognized by the computer in the correct flashing mode.

To resolve this issue, you need to re-flash the firmware: first short the B1 pin to GND, power on the module, flash the firmware using the flash_download_tool software according to the instructions in the ESP32 firmware section under the Wiki, and then reboot to restore normal operation.
