I am getting the following error when trying to flash the ESP-IDF firmware to my ESP32 device:
CMake Error at run_serial_tool.cmake:66 (message):
Environment:
Operating system: Ubuntu on virtual machine ESP-IDF version: 5.1.1 ESP32 device: esp32c6-devkitc- v1.2
I have tried the following troubleshooting steps: Made sure that the ESP32 device is connected to my computer and in the correct mode to be flashed. Tried flashing the ESP-IDF firmware using the esptool.py command-line tool. Tried flashing the ESP-IDF firmware using a different IDE or build system. Tried flashing the ESP-IDF firmware to a different ESP32 device. I am still getting the error message. Question: What can I do to fix this error?

Had a similar message only when I had another Serial monitor opened and connected to that esp32. When i closed that serial monitor it flashed.
