I’m having the same issue, but I’m running macOS 14.5 (apparently I didn’t know there was an update lol) on an Intel MacBook Pro and using Lightroom 13.5.1 and NLP v2.3. The issue was mostly happening when batch processing a whole roll, but occasionally crashed when I was converting a single negative.
As soon as I downgraded Lightroom to 13.4, the problem disappeared.
I have Apple M1 Max on a Mac Studio. From all I am reading from you guys sounds like I would be safe to continue & upgrade my operating system to Mac Sonoma 14.6.1. I am currently running LR 13.5.1.
I am not that brave so does anyone else have M1 Max and completed the upgrade?
Any help always appreciated.
Nate:
I’m still having an issue after upgrading to MacOS Sequoia (15.0) on my iMac Pro, with LR Classic 13.5.1 and NLP 3.0.2.
However it seems I can convert 3 or 4 negatives at a time, but no more, without issue. That’s a little better than doing them one by one, which was my workaround before with 14.6.1…
I was having the same issue with an intel mac. I upgraded to OS 15.0.1 and had the same issue. With a Lightroom version change to 13.4, it seems to have gone away
I’ve had this same issue intermittently on my M1 Pro MacBook Pro Running Sonoma 14.5
I found that the error was thrown in a few scenarios for me.
When selecting multiple RAW files to convert, I noticed it would throw it if one of those images was a DNG (I converted one, forgot about it, and it sat in that roll) NLP seemed to not open when the DNG was selected in the group of RAW
Also If I converted let’s say 2 full rolls. and each roll had a “first image” that I didn’t convert. When I batch selected the whole lot of 2 rolls (including the 2 non-converted images) This error popped up.
in both cases, it seemed the only way to fix this was to restart Lightroom Classic, and then select the multiple images I was trying to open NLP for, but NOT select the DNG in case 1 or the un-converted images in case 2.
Using DNG created from Vuescan and edited with NLP 2.x 2 years ago. No change if I try to reset all settings. Got the error if I try to edit only one or if I try several with the new roll functionality.
Any news on this one? I tried an untouched raw (not negative) and the conversion works fine. But if I try a DNG from Vuescan earlier edit with NLP 2.x I’m not able to edit…
I have this same issue, ran into it today. After encountering the problem, I upgraded to NLP v3.0.2. but the problem persists. I have MacOS 14.6.1 and LRC 13.5.1. I am trying to scan a Silverfast 9 DNG and things worked fine with this workflow until today, must have been the Sonoma or the LRC update that messed things up. The last batch of negatives I scanned successfully was on August 1.
