Cannot import Sony a7 III mp4 video

[Jan27908417mlfs]

Windows 10 Pro / Lightroom Classic 12.3 / Camera Raw 15.3. Fresh install of Lightroom.

I am new to lightroom, and on the trial plan. I have successfully imported photos from folder and via USB to camera, but video fails. If I navigate to the video files during import lightroom shows "Preview unavailable for this file." in each video thumbnail. If I try to import (using "Copy" or "Add"), a pop-up appears saying "Some import operations were not performed" and for each file "The was a problem with the video file".This happens for all video files taken with the camera over the last months since I bought the camera (~100 videos on 5 different SD cards).

I have checked permissions on the folders, purged and expanded the video cache, and ensured that the dynamiclinkmanager.exe is not hanging.

Any ideas of how to fix or troubleshoot?

Can you import still photos from this camera? What is the exact Destination folder selected in the Import dialogbox?

- Yes, I can import photos from the camera.
- I navigate to my SATA drive with the files and chose "Add", so I expect the destination is the source. 
- I am away from the workstation right now, I will give you the exact path when I am back. But it is of the form: "K:/Sony a7iii/project 10/Private/M4ROOT/CLIP/C0016.MP4"
- And I can play the videos from outside lightroom.
- Here is a link to one of the files: https://drive.google.com/file/d/1_VhkDuoLPopFOJ_IRmsDfKZRhXnKNGfD/view?usp=share_link 

My best guess is that this is due to something in my windows installation, but not sure how to troubleshoot and not ready to reinstall windows for a trial.

I think there Lightroom Classic has a limit on the number of penguins that can appear in the photo or video — haha, just joking. That's a lot of penguins!

This file imports correctly into my Lightroom Classic 12.3 on Windows 11. So I am at a loss as to why it won't import for you.

Bwarhahah - thanks! I will see if I can purchase the penguin upgrade 😄

Update:
- It works perfectly on on the system computer in Lightroom CC.
- Procmon shows problems loading VLC. It looks to me like a path is missing a seperator. Could this be the issue? VLC works without problems on its own, playing the file I cannot import. Maybe it is a path specific for lightroom?

SOLVED. I followed this, and it worked! I get thumbnails, and can import mp4! https://www.lightroomqueen.com/community/threads/a-solution-connecting-to-dynamic-link-server-failed...
