cannot save as... with macos 26 tahoe

Just upgraded my mac to 26.0.1 tahoe and cannot do a “Save as…”. There is no field for the new name in the new dialog, and the save button is greyed, it cannot be clicked. A temporary fix is enabling “Use LibreOffice dialogs” in the General settings, this is, disabling macOS windows management.

wondering if somehow related … 168591 – Text files remove original formatting when I reopen them ["Save As" greyed out]
