Thanks. It looks like a bug that is specific to libopus.
I’ll log this issue if it’s not logged already.

It was already logged: Custom audio export. libopus is 'incompatible' codec for opus container · Issue #2117 · audacity/audacity · GitHub

The “workaround” is:

  1. ctrl+shift+e
  2. Select “Opus” as the export format.
