Photos are grayed out in LRC Library Module

[SRBruns]

While traveling, my wife and I took photographs with a Nikon Z6II and a Z8. While on the road, I backed up the photos on an external SSD, importing them into a copy of LRC on a MacBook Air running Tahoe. Everything worked fine.

When I returned home, I copied the files on the SSD onto an external drive connected to a Mac Studio and imported them into LRC on that computer. The Z6II files are fine. The Z8 files are grayed out in the library module, even after processing. They are fine in the develop module. I have been unable to find anyone with similar issues online.

I have imported hundreds of photos from the Z8 onto this computer before with no problem. I'd appreciate any suggestions. Thanks.
