Description of problem:
Trying at least
 $ wpctl status
M 11:38:06.425130            pw.conf ../src/pipewire/conf.c:939:try_load_conf: can't load config client.conf: No such file or directory
W 11:38:06.425202            pw.conf ../src/pipewire/conf.c:963:pw_conf_load_conf_for_context: can't load default config client.conf: No such file or directory
C 11:38:06.425226            wp-core (null):(null):(null): wp_core_constructed: assertion 'self->pw_context' failed
Segmentation fault (core dumped)

How reproducible:
Every time

The two complaints about pw.conf are also seen with:
 $ wpctl -h
M 11:40:55.529114            pw.conf ../src/pipewire/conf.c:939:try_load_conf: can't load config client.conf: No such file or directory
