Fatal Error on compile with ESPHome 2025.8.x for athom-smart-plug-v3

[wmrato]

Unable to Compile firmware for athom-smart-plug-v3, since ESPHome 2025.8.x,
have retried & failed to re-compile up to 2025.8,.2.

Done some research & possibly error is when framework: type: esp-idf is used.
Compile has issues with platformio library not found.

Have tried:-

• Checked the file system via SSH & can see no platformio folder.
  Online fix stated delete platformio folder & reboot to make ESPHome rebuild platformio library.
• Tried Clean Build Files before compiling.
• Restarted ESPHome Addon & rebooted HA OS.

Compiled on:
OS: Home Assistant OS 2025.8.3
HW: ODROID-N2+ 4GB, 64GB
