Additional comments

The issue is similar to #41641. But even cleaning the cache did not solve the issue.

The error is coming from the system plugin for uikit. You should check to see if they have an update

@FrankReisenhofer this is not a bug, the plugin your using needs an update by the vendor please update the plugin, if no update is available you can try and replace in line 4 in plugins/system/uikit3/uikit3.php the JPlugin to \Joomla\CMS\Plugin\CMSPlugin. Maybe this is enough for the plugin to work again.

I'm closing this because it's not an core issue.
