Hi,

Most of the option under "System Settings" in lxqt-config that started with
YaST apart form YaST itself exhibit the similar error symptom 

Below error are traped when run lxqt-config in Terminal

bash: /sbin/yast2 system_settings: No such file or directory
bash: /sbin/yast2 partitioner: No such file or directory
bash: /sbin/yast2 alternatives: No such file or directory
bash: /sbin/yast2 timezone: No such file or directory
bash: /sbin/yast2 hwinfo: No such file or directory
bash: /sbin/yast2 language: No such file or directory

Best Regards
Chris
