The AAC export option strangely vanished in the “M4A (AAC) Files ( FFmpeg)” Format option (other options OK) Easiest way to retrieve AAC?

Export Audio - Formats missing?

Go to Edit → Preferences → Modules. Depending on your version of Audacity you may see several mod-xxx boxes for various audio formats. Enable them all. Or you can delete your audacity.cfg file and when you re-start Audacity it should build a new-clean one. This page tells you where to find it. When you un-install it keeps the audacity.cfg file. Then when you re-install it uses the old settings by default. (I think it asks a question about that.)

Thank-you so much, Trevor. Though I must apologize for not stating (1), that my edition of Audacity is 3.7.7 (Possibly it was very recently automatically updated), and (2), my OS is Sonoma 14.8.5.

My ‘dynamically linked libraries’ for the converter, and there are 9 of them (beginnnng with libavcodec.59.18.100.dylib).

Sorry for any inconvenience.
