Has anyone else experienced this? Curious to know if anyone has noticed this. I have started a report on the bug reporting url for Adobe. HDR Merging 2 raw Sony A7RIV files in latest LR Classic with any ghosting option selected causes a LR crash. It will usually finish the merge but as it brings back up the library grid the program crashes. Tried doing the same in photoshop using bridge to merge the two files in ACR and get the same crash. It works in both LR and Photoshop/Bridge if NO GHOSTING options are selected.

Lightroom creates several temporary files in Working Storage. Working Storage uses the free space on your primary disk. Lack of free space on the primary disk can cause Lightroom, your swapfile and other app using working storage to run out of room and crate. Could this be your problem? 60+ megapixels per merge file can clog up a small primary disk. Could this be your problem?

HD free space on primary drive is 300 GB. LR Cache size set to 50 GB. Don't think this is the problem. Suspecting it has to do with what a HDR Merge w/ghosting requires for two large files and it stepping on LR's main memory management requirements. Redid the test but using the APS-C setting on the A7RIV which yields 27 Mb files vs 62 MB and it worked without a problem. So the issue does seem to be squarely related to file size of the two photos being merged. Adobe responded to me regarding the bug submittal asking if they can have the two files in order to try and duplicate. I sent them a link for both the 62MB and 27MB versions along with the details of my MBP I'm running LR Classic on.
