Problem with importing photos from iPhone X to MacBook Pro

Hello. Today I encountered a strange problem while importing photos form my iPhone to my Mac. As of today I had about 2000 unimported photos on my phone. I connected iPhone to my computer and tried to import them. After some time, about 750 photos were imported and then the process got frozen. I waited for 20 minutes but nothing happened. Then I closed the program and tried to import them again, however, this time Photos stopped to show any pictures on my phone(See picture 1). I tried some tricks but they only appeared again when I restarted iPhone. Next, I tried to import just a couple of photos, and after a about 2 minutes of freezing the message was displayed that Photos could not import the chosen objects because their format is unsupported(See picture 2 and 3).

Info: Both MacBook and iPhone are updated to the last versions.
