Sorry for the slow response, I'm out on fieldwork and haven't had much chance to test it. But it's all fixed now! Thanks a bunch.

Thanks! 4.1.5 installed now and opens the images fine, so I can get on with using that temporarily. Will do. Feel free to use those images for any test/debug purposes needed!

Thanks for the many quick responses! I've updated RawTherapee to the latest version, and still encounter the same issue with JPGs developed from my raw images. However, if I develop them as TIF instead, they retain the same EXIF data but Paint.NET has no trouble opening them (https://www.dropbox.com/s/uqgaw82z47hh01b/DSC_2165.tif if needed for testing). Is there somewhere I can download the previous release of Paint.NET to use until this issue is fixed?

Sure. Too large to upload here, but this is one of them: https://www.dropbox.com/s/4qt5gtbafarftm2/DSC_2165.jpg

With the latest update of Paint.NET 4.2 (July 13 build) I can no longer open JPGs as developed from my NEF raw images with RawTherapee 5.1 -- with earlier versions of Paint.NET I never encountered this issue. Here's the error it gives: Application version: paint.net 4.2 System.InvalidCastException: Variant type 4108 not supported at PaintDotNet.SystemLayer.Native.x64.NativeConversions.FromPROPVARIANT(tagPROPVARIANT* propVariant) at PaintDotNet.SystemLayer.Native.x64.Imaging.WICMetadataQueryReader.TryGetMetadataByName(String name, Object& value) a
