I've got a sketch that works fine, it compiles and runs on a custom 32u4 based board I designed. I program it via ICSP, usingI'm trying to use a genuine Arduino Nano as an Arduino as ISP programmer in Arduino IDE 2.x, flashed with the ArduinoISP sketchand it's not working.

In v1.8.19 of the Arduino IDE I select the comport the Nano appears as, select "Arduino as ISP" For the programmer, select "Arduino Micro" as the board to flash, and then select "Tools -> Upload Using Programmer". The My sketch is compiled, the IDE connects to the Nano, and the flash proceeds as expected and completes successfully.

EDIT: Removed irrelevant comment about what I'm trying to flash with the Arduino as ISP setup.

Arduino IDE 2.x fails to flash 32u4 via ArduinoISP flashed Nano, but 1.8.19 works

I've got a sketch that works fine, it compiles and runs on a custom 32u4 based board I designed. I program it via ICSP, using a genuine Arduino Nano, flashed with the ArduinoISP sketch.

In v1.8.19 of the Arduino IDE I select the comport the Nano appears as, select "Arduino as ISP" For the programmer, select "Arduino Micro" as the board to flash, and then select "Tools -> Upload Using Programmer". The sketch is compiled, the IDE connects to the Nano, and the flash proceeds as expected and completes successfully.

In v2.3.6 of the Arduino IDE (or in VS Code using the "Arduino Community Edition" extension) when I try the same thing with the same steps, the flash fails. It appears avrdude is being told to use a different flasher than what I've selected ("Arduino as ISP") in both cases and I can't figure out what to do to straighten this out so I can move forward using the newer toolchain.

The successful output from the older Arduino IDE looks like this when it starts the process, after building the sketch:

     Programmer Type : butterfly
     Description     : Atmel AppNote AVR109 Boot Loader

     Connecting to programmer: .avrdude: butterfly_recv(): programmer is not responding

I'm also mildly confused about why selecting "Arduino as ISP" shows it using the STK500 when it works, but if I select STK500 from the list of available programmers, it fails. No matter what I select in the Arduino 2.x IDE or in the VS Code extension, it seems to always want to use this "butterfly" programmer, which I've never heard of and always fails.
