Can't run Carla using pipewire : undefined symbol: pw_thread_utils_get

Version, Distribution, Desktop Environment:

Version - 0.3.31 Distribution - 5.12.15-arch1-1, Arch Linux DE - KDE

Description of Problem: Was following these steps to get Carla working with Pipewire; https://wiki.archlinux.org/title/PipeWire#LADSPA,_LV2_and_VST_plugins.

After I run pw-jack carla-rack, I get the following error:

Carla 2.3.1 started, status:
  Python version: 3.9.6
  Qt version:     5.15.2
  PyQt version:   5.15.4
  Binary dir:     /usr/lib/carla
  Resources dir:  /usr/share/carla/resources
Traceback (most recent call last):
  File "/usr/share/carla/carla-rack", line 48, in <module>
    host = initHost(initName, libPrefix, False, False, True)
  File "/usr/share/carla/carla_host.py", line 3201, in initHost
    host = HostClass() if HostClass is not None else CarlaHostQtDLL(libname, loadGlobal)
  File "/usr/share/carla/carla_backend_qt.py", line 96, in __init__
    CarlaHostDLL.__init__(self, libName, loadGlobal)

    self.lib = CDLL(libName, RTLD_GLOBAL if loadGlobal else RTLD_LOCAL)
  File "/usr/lib/python3.9/ctypes/__init__.py", line 374, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: /usr/lib/pipewire-0.3/jack/libjack.so.0: undefined symbol: pw_thread_utils_get

And just to clarify, pipewire is working well (attached output of pactl info;

Steps to reproduce:

Followed by

^ here it fails.

Actual Results:
