Bug Description

On Ubuntu Impish.
Since the system was updated 2021-06-15, Unity is not loading properly, if at all:
Lightdm is not working anymore, the system loads to a black screen with a cursor. Gdm3 does work and is able to load the Unity session.
Once in Unity, I’m greeted by an error message instead of the regular Ubuntu background:
“Something went wrong.
An error occurred and the system can’t load.
Log out and try again.
‘Close session’ button.”
Using the Alt+launcher number, I am sometimes able to start an app, and after several, Unity may load, launcher and all, but the error message stays in the background.

The environment theming and icons have all changed and Unity Tweak Tool can’t switch them back. GTK may be involved.
Some features have been lost:
I can’t start the calculator from the keyboard shortcut, number lock is not enabled on start up
Settings > Power doesn’t return any energy readings.
I can’t put the system to sleep. If I hit Fn+F8 on my keyboard, the session kinda resets and most (all) my apps are killed.
Upon first loading the sessions, there is no cursor. If I manage to load and access Nemo, then the cursor appears with a big X, and eventually shows an arrow.
Etc.

According to Khurshid Alam, “this is due to an update of gsettings-desktop-schemas to 40. A fix is in progress. So you can either wait for the fix or downgrade gsettings-desktop-schemas meanwhile to 3.38 and it will work.”
