Solution 1: The available space of the C drive is too small
When we have free space on the C drive When it is within a few tens of K or less than one megabyte, our thumbnails may not be displayed. At this time you should clean up the space of the C drive. I suggest you read the "Manually organize the C drive file, but also a clean C drive."
