LR Classic 9.4 suddenly not importing videos.

[The Lensman]

I have been importing .mov videos shot on my Nikon D850 for a long time. Now suddenly I get the error An unknown error has occurred while reading the video file. Connecting to Dynamic Link server failed. (1)

I have tried solutions posted here but nothing works. I need help.
