LR freeze at ~170 pictures processing. 32 GB memory, ~15GB pagefile. DNGs imported from Samsung Galaxy S23 Ultra at 12 MB size. Graphic card NVIDIA 5070 Ti. Task Manager memory peaks at ~95% before freeze.
Thank you for sharing the screenshots and the detailed description.
Here are a few targeted steps to help us move forward with diagnosing this:
Does the freeze happen consistently around the same count (~170 files), or does it vary depending on the batch size or image type?
Run Lightroom once as Administrator.
Temporarily disable GPU acceleration under Preferences > Performance > Use Graphics Processor and try running the same batch again.
From your screenshots, the process hits ~95% memory usage before freezing. Please try running the same batch after closing all background applications.
Reset preferences. Quit the app and relaunch it while holding down Shift + Alt. A dialog box will then appear, allowing you to confirm and reset your preferences to their default state
Please share a few of your sample DNG files privately so we can test them. Additionally, please share your system information from Lightroom (Help > System Info) and copy and paste it here.
