Sorry about the report. I Found the resolved the problem.

After purging carla and related packages and reinstalling, everything
works now.

The commands I did to resolve the problem was:

sudo apt purge carla
sudo apt autoremove
sudo apt install carla

I don't know what caused the error, but the library still doesn't have
the symbol carla_cocoa_set_transient_window_for, but
/usr/share/carla/carla_utils.py doesn't have the call to it anymore

Title:
  Carla doesn't work

Status in carla package in Ubuntu:
  New

Bug description:
  I am running Ubuntu 21.04, the carla package is 2.3.0-0ubuntu1

  Carla crashes with this message:

  Carla 2.3.2 started, status:
    Python version: 3.9.5
    Qt version:     5.15.2
    PyQt version:   5.15.4

      func = self._FuncPtr((name_or_ordinal, self))
  AttributeError: /usr/lib/carla/libcarla_utils.so: undefined symbol: carla_cocoa_set_transient_window_for

  Compiling the last version from github
  (https://github.com/falkTX/Carla) works as expected.

  Using nm I was able to confirm the libcarla_utils.so from the Ubuntu package doesn't have the symbol carla_cocoa_set_transient_window_for
   present, but the compiled version has.
