After this month’s big update, there were some issues.
I have 2 user accounts, on one everything is ok, on the main user however the “dash to dock”, the desktop icons and other customizations I had have disappeared.
Advice, solutions or explanations? 
Hi, it sounds like you’re extensions have been disabled, please check the output of:
gsettings get org.gnome.shell enabled-extensions
If the output is empty, check the output of:
gsettings get org.gnome.shell disable-user-extensions
In case the value is true, you can re-enable the extensions by running:
gsettings set org.gnome.shell disable-user-extensions false
You can also use the Extensions tool which should be pre installed I guess to check for enabled/disabled extensions.
