View "Assigned" disappeared / deleted

Hello M-Files Community

We've somehow managed to delete the "assigned"-View.. when I declare "assigned" as my home-view, the error from the screenshot appears:

within the "Other views" the view is also no longer visible, so i guess we've deleted it somehow.

Is there a way to restore this view or create a new one and define this one as the default "assigned" view?

Many thanks for your support in advance and kind regards
