Colorizing Ortho - Process Exited With Unknown Error

Im on latest version v1.13.12.
When processing r3 pro v2 data, porcessing is failing on the final step Colorizing Ortho’ with 'unknown error.

When I re open Rock Desktop, I can view the processed point cloud and trajectories but obviously the ortho is not generated.

If I run processing a second time, it works without a problem.

I’ve logged with support, will report back with any findings.

Thanks
Jason
