Same thing here! Things worked fine until iOS 18.1.1 After upgrading to iOS 18.2 any new videos taken with my Iphone 15 Pro Max do not show thumbnails and metadata in Windows 10.
This is how you can solve the problem:
- Download the free "exiftool" for Windows from exiftool.org
- Copy the videos in the same directory as exiftool.exe
- Type this in the command line
exiftool -m -P -overwrite_original -Keys:FullFrameRatePlaybackIntent= *.MOV
or
save the above command with a text editor as convert.bat and click on convert.bat
This will process all the videos so you can see the metadata and thumbnails in Windows 10.
