it gave me the following error:
The project sample rate (44100) and bit rate (24 kbps) combination is not supported by the MP3 file format.

You forgot this step:

Before exporting, set the "Project Rate" to 16000 (lower left corner of the main Audacity window).

I still would like to know if I could do something to export to m4a as before so I have all the files with the same format.

You could use Audacity's command line exporter (the "external program" option): https://manual.audacityteam.org/man/exp ... ogram.html
You may need to refer to the FFmpeg documentation to work out the correct command line options: https://ffmpeg.org/ffmpeg.html

Also note that FFmpeg has several different codecs for M4A. The available encoders are set when FFmpeg is compiled. More info here: https://trac.ffmpeg.org/wiki/Encode/AAC

Personally I think that due to the difficulties of using M4A on Linux, it would be better to use a different format, such as Opus or MP3.
