Problem/Motivation
The drush locale:export fr > fr.po don't export any .po file, the command stop silently.
Tested on legacy code and on a fresh DDEV install.
Steps to reproduce
Launch drush locale:export fr > fr.po
When launched with the -vvv option, the command don't stop and block after "[info] Try to validate bootstrap phase 0 [0.6 sec, 41.61 MB]"
