Updated Lightroom Version 12 Catalog issues
I have updated to Lightroom 12.01 and when I opened my current catalog I recieved the below screen

I updated the catalog and now have missong photos and folders, I check the location where the old folders were stored (on a external hard drive) and the photos are still there but will not come over to the new catalog/version of Lightroom.
I have a new Mac Book Pro running Ventura 13.0.01 I havbe had no issues until this update.
Can someone let me know if theis is a known issue, and how I canuodate my catalog and hopefully get the old catalog uopdated correctly.
**I am not very computer savy, so hopefully i have provided hte correct amount if infoemation for a fix.
