TIFF files not displaying in LR Classic after Mac Sonoma 14 install

The issues have gone away. Not having any problems currently. But thanks to any who responded!

LR Classic 12.5 has been installed on my iMac for a week and working fine. Not being aware of issues related to Mac OS Sonoma 14 I installed that an hour ago. I reopened LR Classic and I notice several issues. When I try to exit LR I got a message that it was still writing XML data blah blah blah. A few minutes earlier I had opened several DNG files from LR in Photoshop, did some sharpening and saved the files. I've done this for many years. The newly created TIFF files would always immediately appear in LR Classic with each file right nex to the original DNG. Nothing is appearing now except the DNG's. Also, I applied the AI noise reduction to several of these DNG's and now those files have disappeared. Any idea how to deal with this? Thanks
