Export starts and the progress bar does not move, but you can cancel
export? Are you using `jack2 --version` is less than 1.9.11 ?

If both are true: update jack or use a different engine to export.


Another option: some plugin in that session does not play nicely with
freewheeling. and a 3rd possibility: Are you using the alsa-loopback
device with jack (alsa_in/out)? On some systems this is apparently
breaks jack freewheeling.
