No such file or directory: '\\esp32\\bin\\bootloader_qio_80m.elf

I please need some assistance. I’m trying to upload a program to my ESP32 Dev board. I then recive this error: FileNotFoundError: [Errno 2] No such file or directory: ‘\esp32\bin\bootloader_qio_80m.elf’[6556] Failed to execute script ‘esptool’ due to unhandled exception!
I’ve upgraded my computer to windows 11 but before the upgrade, I used to be able to upload programs to the ESP modules with no problems. My computing knowledge is limited so any help would be appreciated.

Hey!
It looks like the upload process is failing because it can’t find the bootloader file. This might happen if the toolchain wasn’t installed properly after your Windows 11 upgrade.

A few things you can try:

  1. Reinstall the ESP32 board support package in your Arduino IDE or PlatformIO — this should restore the missing files.
  2. Check your file paths — sometimes Windows updates can mess with environment variables or move folders around.
  3. If you’re using PlatformIO, try deleting the .pio folder in your project and rebuild it.

let me know if this works for you or not.. ill be happy to assist you further :100:
