This has happened on occasion one the years. Restarting seems to fix the issue, but anyone know what causes it?

It seems to be related to large files, but I'm not 100%.

Within Finder I can drag and drop some files but not other files. The problematic files just won't drag. I can select them, but not drag them.

Anyone else run into this issue?

I can drag and drop the first file shown above (unselected), but the second file cannot be dragged.
