Hello everyone on the forum. If you, like me, encountered the same problem (the pipewire process uses 100% of one CPU core) after recent updates, and for some reason you have kernel version 6.1 (linux61) installed - there is a solution: update the kernel to linux613 or linux66 and reboot your device, this should help restore normal system functionality.
Screenshots before and after kernel update:
I cannot reproduce this.
Switched from 6.12 to 6.1 to test and all works fine.
The problem has recently arisen for some manjaro users, maybe it is a conflict of some specific packages that are installed by all these people

Seems it is fixed by Philip Müller already.
I tested today, so seems the patch is working
