Description
On macOS Sonoma 14.3 MacDown 0.7.1/0.7.3 appears to be unable to store entries in the recent file list in File → Open Recent. The entries are blank and, when selected, generate an error dialog:

I see this behaviour on two separate Macs both running macOS Sonoma 14.3.

Research direction
Start by reproducing the blank File > Open Recent entries on macOS Sonoma 14.3 with MacDown 0.7.1 or 0.7.3, then trace the recent-file handling from that menu. Done means recent entries show valid filenames and selecting one opens the document without the “(null)” error dialog.
