Video Files won't import - "There is a problem with the video file."

Hello Sameer,  I am importing the video from the computer hard drive.  These are .mp4 videos from our phones (Samsung Android).  They are automatically uploaded to Onedrive and synced to the "Camera Roll" subfolder of my Pictures folder on my computer.  I occasionally import all files and videos from the "Camera Roll" folder into Lightroom.  As of the end of December, video files no longer import and I receive the message "There is a problem with the video file."  The video file is a supported format, plays without issue by several video players, and they appear to be exactly the same videos as I have imported in the past. 

Welcome to the Lightroom Classic community. I'll help you figure this out.

What mobile device are you working on & have you changed the cable to connect to the machine? Try these things & let us know how it goes.

• Try to copy the videos to the computer & then try to import them - does this work? If yes, try deleting the mobile device drivers from the computer & try connecting again.
• If videos don't import from the internal drive, try this: 
  Lightroom Classic uses Camera Raw Plugin for images & DynamicLink for handling video files.

  Try the steps shared in the article first: https://helpx.adobe.com/lightroom-classic/kb/troubleshoot-video-issues.html

Let me know how it goes.

Thanks!
