Can't view DNG files either in Preview or with Quick Look

I converted some image files to DNG format using Lightroom. macOS Monterey can't open these files, either in Preview or using Quick Look. I have tried both lossy and lossless DNG conversion, without success.

sample1.dng from https://filesamples.com/formats/dng can be viewed in Preview 11.0 (1033.4) on macOS 12.6.2 (21G320). Check the differences between that image and your images.

I tried using opencore and following the guides but my 2010 MacBook Pro can't find any wifi networks which means I can't install Monterey. Does anyone have any fixes to this?
