Here is the console at this point:
MatchPhotos.select (1/1): downscale = 1, subtask = select, generic_preselection = on, reference_preselection = off, filter_mask = off, mask_tiepoints = off, filter_stationary_points = off, keypoint_limit = 60000, keypoint_limit_per_mpx = 1000, tiepoint_limit = 6000, guided_matching = off, exclude_corners = off, data_folder = //Be7960x/e/DVDSSP/PS/DVDSSP.files/0/0/point_cloud
loaded matching data in 0.01 sec

It will sit here for a long time and then move to "setting point indices", which also takes a very long time
