There was no issue with scanning and downloading photos on my computer. But in the moment I opened first photo my computer went down. I tried to reset computer and open it in safe mode but it also didn't work. I am now reinstalling Windows which meant losing all data I had. There was also some error when I was downloading photos on my phone but it doesn't look like it done anything - I think whatever was wrong with it was blocked as some of the photos didn't download.
