Rhino WIP possible bug in last release

I find that on R9WIP when I save a file now, the thumbnail doesn’t appear, instead, just the Rhino Logo. Not sure if this is a bug or not, but, I miss pressing my space bar a visually viewing the model thumbnail to make sure it’s the file I’m looking for. I’m using Mac OS Tahoe 26.3.1 (a)

Not sure if anyone else has noticed this potential bug.
