More video thumbnails in Explorer.
Overnight, new videos created on my PC no longer display thumbnails (Windows 10 x64 Pro 22H2 last update) except for .wmv and .avi Those who had their thumbnails cached kept them. It's only for video...
Thumbnail display issues, especially with videos, can be tricky because they involve both Windows Explorer's caching and the underlying codecs or thumbnail providers. Since you've already tried clearing the cache and the problem only recently started.
