I started using 2024.2.1 and just found that my install won’t let me export clips with audio while doing it in the background, it just works exporting as a foreground task. I tried the audio from an imported MP4 Quicktime, I tried importing the audio as an AIF and I tried exporting the audio from flame as a WAV (which never happened) and none seems to work. Except when doing it in the foreground.
When doing it as a background process it just hangs there at 0%.
No problem here on a 2019 MacPro But running the latest Sonoma 14.3
Maybe the WiFi is on by accident?
Delete everything from the BB task list, restart the Mac…?
Maybe try a cold shutdown(unplug the power and everything from the Mac, wait a couple minutes).-
Sorry can’t be of more help, just guessing here on things I’ve done in the past.
