Media-Library only works in ‘List’ mode

The media library can only be displayed in ‘list’ mode, not in the default grid mode. The reason is probably a bad image or document. Please call the following link before clicking on the ‘Media’ menu entry on the left side for the first time. After this WordPress remembers the list mode and the ‘Media’ menu entry can be used as usual.
