Unable to load Photo from iCloud

Hello,

I am getting the following error message: "An error occurred while loading a higher-quality version of this photo." on my iphone 15 pro max.

Previously I have manually imported a big album (~3000 photos and videos) in my Macbook Photos library. I can see all photos in this album being correctly visualised on my Macbook and also on icloud.com. Problem is with my iphone Photos library where these photos cannot be loaded. My internet connection is pretty good and also I have a bunch of free storage (400GB free) on the iphone. I haven't tried with enabling "Download and keep originals" because my Photos library is quite big and will fill up my internal storage.

Any clue how I can fix that?
