> Could you provide some details on how you set a profile which isn't available?

I invoked powerprofilectl and "fixed" the performance profile using that. And then gnome-control-center would throw a fatal assertion failure (UI cannot open, basically total non-function of the app), and stop working. If the profile setting is rolled back using the same powerprofilectl, it can be opened again. The patch from upstream converts this error into a logged non-fatal warning.
