Image thumbnails not displaying in Finder
MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)
2.3 GHz Dual-Core Intel Core i5
8 GB 2133 MHz LPDDR3
Intel Iris Plus Graphics 640 1536 MB
Since installing the latest update OS: 12.2.1 Monterey, my JPEG, JPG and PNG images only show as a generic icon, no Thumbnail previews. Some images are not affected, but I cannot find a common factor - e.g. age of file - to explain why.
I have checked that Finder > View is set oto View as Icons
MacBook Pro 13″, macOS 12.2
