I've just checked Camera Raw 15.2 and Lightroom Classic 12.2 and they can convert to DNG and process the converted DNG file

 

Files converted from Lumix DC-S5M2 Raw (RW2) files using DNG Converter and imported into LrC 12.2 can also be processed without issue.

 

I'm using macOS 13.2.1 Ventura

 

May be you could upload an original and DNG version of the files you're having problems with to Dropbox or similar, then post alink to same when you next reply.

After converting the RAW files to DNG format

Is that conversion via LrC, or from a third party RAW converter?

Ja, die Konvertierung erfolgte über LRC und auch über Adobe DNG Konverter!

das Problem tritt nur auf, wenn die Option "lossles compression " gewählt wurde!

No third party software, only LRC and Adobe DNG Converter! The problem starts when the option ist set to lossless compression

Hmm, not sure where you're seeing an option for lossless compression as that that's the default conversion for DNG. Are you sure that you're not confusing 'Lossy Compression' as shown on attached screenshot of DNG Converter.

 

Edit: Attempting to use 'Lossy Compression' results in 'not supported', but this option is only used when lower quality demosaiced images are acceptable.

Ohnmacht goodness! You are right!

I was wrong! I had tried the "lossy compression" option and then it got the error! the file was offered as a preview in LRC with a note, but it could not be edited! if this option is not set, then the files will also be properly converted to DNG! thank you for your hint!!!

It may still be a bug. Therefore, flagging for @Rikk Flohr: Photography to check internally.

I am leaning towards a bug here. I can replicate with Lossy Compression enabled.
