Photos app on Mac not syncing all photos from iPhone
I have been manually downloading photos from my iPhone 12 pro to my iMac using a cable. Generally this process works smoothly. However, today after connecting the iPhone to the mac, the Photos app on the Mac is not showing me all the photos available to be downloaded. It's stopping at a certain point, beyond which it just shows me blank squares instead of the new pics for downloading.
I have tried restarting the phone and the computer but the problem is still there. It just loads up the photos from the phone upto a certain point and then stops. This problem was not there earlier. Screenshot enclosed for reference.
