Texturing: RC 1.5 texturing hangs, RC 1.4.2 works fine with same dataset and workflow

Tested on the provided project, it looks like the unwrap was provided, but then the process stuck. I also checked the Task manager and there wasn't almost any activity for RealityCapture.

1. Open the project from: [Link Removed]
2. Re-link the images and LSPs
3. Set Fixed texel size for texturing
4. Texture the final model

When processing a photogrammetry dataset and only  20% of the photos are used for texturing, RC 1.5 hangs at about 40% every time, but the same data and workflow works flawlessly with RC 1.4.2. We are using color-correct DNG with full-res previews. Smaller datasets works fine in 1.5 using 16-bit TIFF or DNG.
