Downgrading the Espressif esp32 board library to 2.0.7 through the Board Manager fixes the problem for the time being. (The problem is likely this commit: https://github.com/espressif/arduino-esp32/commit/b98255d8d1be7280e767f15a8c759e13e00f4b4a)

[thomergil]

@botletics curious to hear your insights on this because, as it stands now, this code is stuck with ESP32 v2.0.7. Thank you.

[botletics]

In Arduino 2.1.0 it compiles fine for the boards in "ESP32 Arduino" in Boards Manager v1.0.4

[thomergil]

@botletics , see above. The problem is ESP32 v2.0.8.

[thomergil]

@botletics, were you able to compile it? (The problem isn't Arduino, but ESP32 v2.0.8.)

[botletics]

It compiles for me on v2.0.9:

[thomergil]

@botletics, confirmed. Thank you.
