source combo in apply image doesn't show anything except current pic.

Hello

I can't anymore choose my source image (DSC_1780) from the combo box in apply image. It worked fine until ... just now. Nothing has been updated, i've just opened my computer and tried to work on my first photo of the day.

Yesterday i could choose DSC_1780 (or anything else) from the source menu.

Same size for all photos. I'm using photoshop 2021 on a mac, just like yesterday... 

Thank's in advance for any tip !
