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 💯
