Critical -- GLib-GIO-CRITICAL

I have been struggling to figure out this. An almost daily system freeze. Sometimes mouse cursor, sound will still go while all froze. I have tried turning off extensions 1 by 1 and all of them. Not real sure what else to look for.

GLib-GIO-CRITICAL: g_bus_get_sync: assertion 'error == NULL || *error == NULL' failed

Will investigate this, but on my end is not present. Are you still having the manjaro-gdm-theme installed somehow?

I get two same error messages in Manjaro Gnome in VM and laptop too. But I ignore them and can not reproduce your issue (froze).

The only theme I have changed is icons.
