P: Cannot merge panorama after updating to 10.14.6

BTW a few weeks are far too long - started a tif-export 8 hours ago (14 cr2-images), system has not finished it by now! LR is unusable!
EDIT: ok, now it's finished... maybe the system was in stand-by because I turned off the screen. Despite this I would really appreciate it if someone official will prioritise this.

Does Adobe reproduce it? I mean, none of the reps has mentioned by now that they will take care of this problem.

> Now that you are able to reproduce the problem, what's coming next?

Having been able to reproduce it on a specific machine, we're a lot closer to Adobe being able to reproduce too. When they can, they can then start figuring out the cause, and then a solution. Then it'll go through testing and then get pushed over to the downloads team to get an update out. Realistically, probably be a few weeks.

Exporting TIFs based on CR2 uses also only one CPU-core... it works but it takes much more time than usual. Maybe not only a DNG-problem...

As far as I can see LR uses 280% of CPU (3 cores) while creating the HDR-preview but falls back to nearly 100% (1 core only) when really creating the DNG, with or without graphics acceleration. Seems to be a problem with the CPU, maybe (Intel core i7 3,2GHz here).

A new business opportunity : ). BTW, I’m using a 2015 27” retina iMac with I7 processor and SSD that has full graphics acceleration enabled if that helps narrow down the issue. macOS 10.14.6

Dear Robert, what about establishing a HDR- and pano-merging-service for the desperate ones? 😉

Now that you are able to reproduce the problem, what's coming next? Is there a chance for an update within the next days? Has Adobe tested this issue with Mac OS 10.15? Please excuse that I'm quite impatient - would like to finish my jobs here but without HDR and panoramas it's not possible. Don't really want to create a non-RAW-panorama with another software but if there will not be a solution available for this problem very soon I fear that I have to because I have to finish the jobs...

Aright, so cancel my previous note about everything working again... I clearly did not try some of my larger panos. Back to status quo -- Lightroom is not merging my larger panos on 10.14.6. 

To help with the debugging of all this, I've recorded a video (and some curious CPU usage) showing which ones I can merge and which ones I can't... along with disk space, memory, etc. As I note in the video, it's almost like Lightroom loses interest at a certain point.

Here is a link to the video:
