I managed to fix the GDBus.Error by temporary disabling "Hide all processes if not owned by the user" and the CWP update command worked fine:
====================================================

Redirecting to /bin/systemctl restart cwpsrv.service
Redirecting to /bin/systemctl restart httpd.service
Redirecting to /bin/systemctl reload httpd.service
Redirecting to /bin/systemctl reload nginx.service
Redirecting to /bin/systemctl reload httpd.service
Redirecting to /bin/systemctl restart httpd.service
I restarted all CWP Services but still all addons scripts doesn't work
Any other idea to fix this issue?
Thanks
