Lightroom Classic Issue - "Photo is Already in Catalog"
I've been using Lightroom desktop for years, and have recently started running into an issue when importing new photos. I'll put in my SD card, but in almost every case, a large number of pictures will be greyed out and not able to import, as Lightroom sees them as already being in the catalog.

I've restarted Lightroom many times, formatted my cards, and tried almost everything else I can to fix this, but I've hit the end of my ability to troubleshoot this.
Does anyone have any input?
