Gnome-shell consumed CPU, disabling Ubuntu AppIndicators solved it

Wed Feb 08 2023 00:00:00 GMT+0000 (Coordinated Universal Time)

Ubuntu 22.04 LTS

  1. sudo apt install gnome-shell-extension-prefs
  2. Open the Extensions app
  3. Disable Ubuntu AppIndicators

That was enough for me. Enabling them again also worked.
