ESP32 Arduino failing to initialise since August 2022

For support of C++17, we switched to the unofficial ESP-IDF from Marcovannoord.

With the latest stable versions, there are no problems when using C++17, see What's the latest on using C++17? - #4 by maxgerhardt.

platform = espressif32

I don’t think using the newest platform code is a good idea here when you want to use the older fork stuff, as I remember it people were doing that in the time where Arduino-ESP32 was supported at 1.0.6 but 2.0.x came out and it wasn’t supported yet. So, a better choice should be platform = espressif32@3.5.0 in accordance to the releases.

Bad package version 1.22.0-80-g6c4433a-5.2.0``

This seems to be coming from the PlatformIO core. If you have a working machine, open a CLI and ask for its pio --version. In the non-working machine, also open the same CLI, and uses the pip as designated by the pio system info command to pip uninstall platformio and pip install platformio=='yourversion'.

I also tried switching to the newer official ESP-IDF version from Espressif (see here) and while that seems to resolve the initialisation issue, I get a bunch of compile errors instead.

When you use the regular new platform with the regular arduino core version 2.0.4, you already have ESP-IDF v4.4 as the base, see arduino-esp32/tools/sdk at 2.0.4 · espressif/arduino-esp32 · GitHub. What are the compile errors you get with this?
