Photo disappears when choosing aspect ratio

[Claudia Finke]

I found a bug - I have a collection with photos, marked with stars, and I wanted to change the format in order to post on Instagram. When I chose the format 4:5, the selected photo vanished from the previews at the bottom of the screen. Ctrl+Z brought it back, but not with the new format of course. I reinstalled 11.3 again and am waiting for the next bugfix.

Solved! I had landscape format selected in the library module and 1:1 for Instagram is NOT landscape of course, so the photo disappears...

Thanks for posting the solution. It's not an uncommon mistake, and it's quite mysterious when it happens.
