fix(launcher): show log init errors in GUI mode

When the launcher fails to initialize the log file in GUI mode (non-console),
the error message was being written to stderr which is not visible to users.

This fix re-enables console logging before logging the error, ensuring that
users can see the error message even in GUI mode.

Fixes #1734
