Pre-existing Clips in Bin are now only audio files

I'm at the end of my project and have a ton of clips stored in bins.  But as of today i noticed that when I retrieve a clip and put it on timeline they are all only audio files.  Of course, they were all originally imported correctly, they have been "binned" for a while and I have retrieved all of them multiple times with no problem.  Only thing that might have led to this : 1. I exported a version of this yesterday but kept the project active to fix a few minor problems  or 2. The program updated to Adobe 2023 a couple of weeks ago and I am just now noticing the missing video.  (i havent retrieved a video in a couple weeks).  Any clues or suggestions?
