I recently upgraded to an M3 Macbook Pro and moved my Lightroom catalog over (LR Classic 13.5.1). Everything works fine, but the videos won't preview or play. The video files are all fine, and I can play them in Finder.
After trying everything from reinstalling lightroom to deleting caches and preview files and plugins to ensuring that Lightroom has full disk access, I came across a post somewhere that downgrading to LR Classic 13.1 and loaded an old catalog and the videos work perfectly.
I would stay on 13.1, but the old catalog doesn't have the last three months of my photos. This appears to be a bug.

Your first step should be to upload a sample video to this forum so we can look at it. Is that possible?

I meant one of the video files that doesn't work - not a recording of it not working! 😉

Well that's not good for me, then. I'm out of ideas.

I don't see in your description of attempts a reset of your preference file.
This procedure works for both Lightroom Classic and Lightroom Desktop.
If you are using Lightroom Desktop, it can change your local storage location. Please review this setting after resetting preferences.
Reset Procedure:
1. Close Lightroom.
2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.
3. Overwrite the Preferences when prompted by the dialog.
4. Close Lightroom.
5. Restart Lightroom.

I did try that both using on-load method and by deleting the file in the Preferences folder.

I wasn't able to complete those steps but I did create a new catalog and I imported videos into it without any issue.
So I'm starting to believe that the issue is probably cause by the fact that the video files are in Google Drive. I've used Google Drive as the "server" for almost 10 years without any major problems. Either there is something wrong with the files or the catalog. But since I don't have nearly enough hard drive space to cache all the photos and videos, I'm afraid there might not be a solution.

For whatever reason, the videos are not working on any catalog, new or old. There must be somethign wrong with the computer.
