Issue with importing files

Lightroom newbie here.  I am struggling with importing images into my lightroom classic library.  I got an initial set of 350 odd images imported, but since then, even if it is just 10 images, the import mechanism freezes then eventually says not responding and to close program or wait.  Waiting never works and eventually I have to close.  Am I missing something simple.  Thanks in advance

I am using Windows 11, most images have been previously worked on and are jpeg files
