Videos in Lightroom Catalog will not play. No video controls or black screen appears

All of thevideos in my Lightroom Catalog will not play w    hen I double-click on them.  Mac OS 13.6.7 , 3 GHz 10-Core Intel Xeon W

i get either a photo without video controls, or a black screen. If I show the videos in the finder, I am able to open and play them with Quicktime player.

What can I do?

In addition, there are  videos and live photos from my iPhone which will not import

Here is the error message:

Here they are in the finder:

Thanks.
