I am having trouble with DNG files

Good Afternoon

I have a 2013 MacBook Air, i7, 8gb ram running OS Sequoia. I take photographs with two Leica Cameras and their only raw output is Adobe DNG.

Ever since I upgraded from OS 15.7.2 I have been unable to open DNG files. If I use QuickView I just get a black box on display. When I attempt to use Preview, the app crashes and I get an Error report. If I place a random DNG file on my desktop, it will show correctly as an ikon.

I read that somewhere this also occurred with OS 15.5.0 but that Apple had since fixed it.

If I open a photo editing software (I don't use Photoshop or Lightroom) the files appear as black boxes until I edit. After that, they show up.

I have upgraded to 15.7.4 but the issue still occurs. I also have a Mac Pro 5,1 running 15.7.4 and I can view and open the files fine.

I can not seem to find anything else on the Internet. I am also not sure if there is a minor incompatibility with my system or if it is an OpenCore issue.

Any suggestions would be greatly appreciated.

p.s. I may just create a fresh installer drive and reinstall the software from scratch.
