In the develop module, each time I hit "Previous" and/or Copy and Paste (Command C/V) I get this Internal Error. Lightroom 7.3.1 Mac 10.13.4

Consider how someone else might reproduce this error, which is the first step to fixing the issue. 

In your other post you specify it only occurs with one particular camera, and the error message mentions something about camera profiles.

At a minimum, can you provide the camera model, the profile specified for the photo you are copying settings from, and the profile of the photo you're copying the settings to.

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.

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!
