That’s probably related to this needed work: Revert any changes toward pipewire instead of PulseAudio in Crimson for Librem 5 (#2) · Issues · PureOS / Tasking · GitLab
I added a comment mentioning this issue as well.
As I understand it, Debian has changed to Pipewire (from PulseAudio) in Bookworm, but this needs more work on the Librem 5. We are going to stay with PulseAudio on the Librem 5 for Crimson and do the Pipewire transition in Dawn.
The recent work to fix synchronization might have brought in more updates from Debian leveraging Pipewire. We also can’t guarantee that existing Crimson installs on the Librem 5 will be able to update correctly right now, things may break if we need to change configuration but don’t have the necessary migrations in place yet. (I think you know that already, stating for everyone’s awareness 
)
At the end of this project, Crimson will be upgradable from Byzantium (on both Librem 5 and PCs). However, Crimson installs made before that point might have to be reinstalled. We’ll do our best to minimize that need, of course.
