After loading Monstree test dataset, computation completes instantly and then "Nothing to compute" if I retry

[mikjsmith]

I downloaded 2025.1.0 on Windows and loaded the Monstree3 dataset. The images import (green icons against each image), but then when I "start" it completes instantly with no output. If I click start again I get a "nothing to compute" log output.

Below is the logfile data from the command prompt window.

Whats gone wrong that stops any computation?

Thanks from a newb!

[13:51:48.869338][warning] Some image(s) have no serial number to identify the camera/lens device.
This makes it impossible to correctly group the images by device if you have used multiple identical (same model) camera devices.
The reconstruction will assume that only one device has been used, so if 2 images share the same focal length approximation they will share the same internal camera parameters.
3 image(s) are concerned.
