Lightroom Classic: Bad argument #1 to 'isCameraProfileMatches" (string expected, got nil)

Hi...Thanks for your comments. I'm using a Leica M Monochrom which I've been using for years. This issue has just arisen today and it's driving me nuts because I'm trying to get through a few thousand pictures. The profile selected and the only option is "Monochrome." With my other cameras, either "Embedded" or one of the Adobe profiles is available. I'm simply going from one "edited" image and clicking "Previous" or trying to copy and paste. 

Hey thanks! Any idea on when an update on this issue might be coming? 

Still outstanding? Major pain in the neck! Thanks.

Yep! Agreed! Would really like for this to go away! Have you found a workaround? The only thing I can come up with is to create a preset and instead of hitting “previous,” I click on the preset for each image. I have to update the preset every few pictures. Major pain in the neck! I haven’t updated my desktop yet because of this, but my I can’t seem to revert my laptop to the previous version.

Thanks, I did work that out but it's hardly convenient. Can't believe that it's this difficult to solve. Waiting with bated breath!

I too get this error, in case any more evidence was needed ;-(

Woohoo! Thank you very much! I’ll give it a try ASAP!!

Great fix! No issues at all! Thanks a ton!
