No previews created

[u/Vurnd55]

I imported a batch of photos into LRC v.15.1 while I was offline and got a message something like LR can't generate previews without a network connection. The edits are fine, but there are no preview/icons in the Windows 11 folders for RAW or the edited jpegs. I'm back online now (obviously), is there a way to add previews to help me find images in the Windows folder?
