Lightroom Classic doesn't import full folder of photos and is stuck importing halfway

I'm learning Lightroom and have run into an issue when importing a folder of raw files. I am trying to import a folder of 47 photos but Lightroom only imports 28 photos out of the 47 and the progress on the import bar gets stuck at just over halfway point (it just says it is still importing but it doesn't move, the software isn't frozen and I can still do other things). I have cancelled and tried again with the same result and have tried doing the same with the 'suspected duplicates' option turned off. I'm using Lightroom classic version 11.0.1 on Windows 10 version 10.0.19043.
