[guglielmino]

This error seems related to some constants names changed in driver/adc.h
M5EPD.cpp starts defining a constant as below

#define BAT_ADC_CHANNEL ADC1_GPIO35_CHANNEL

Looking in adc.h it is clear that name of this constant is changed

...
 ADC1_CHANNEL_7,     /*!< ADC1 channel 7 is GPIO35 */
...

This is confirmed b the compiler output that suggests to use ADC1_CHANNEL_7 instead of ADC1_GPIO35_CHANNEL.

Btw, this issue seems fixed looking here, but the library linked by the Arduino boards manager JSON file is still broken.

Is there any way to solve this?
Still the same problem :(

I think these errors boil down to installed libraries I'm not sure which ones yet. The versions of those libraries is very important also.
For example the ArduinoJson Library Version 6.12
