Error loading tiff images as a 3D model

I am trying to load 15 tiff images which are basically images taken at different z slices and create a 3D model out of it. When I try doing this using the Image Stack option under Slicer Morph, the load button remains de-activated. Could anyone advise on what I might be doing wrong? Alternatively, when I try to load it using the ‘Add Data’ option, even though I de-select ‘Single output/ file’ and select ‘Volume’ option, I keep getting error messages of the kind shown below.

Any idea why this might be happening?

  1. Upgrade to the latest stable (5.10), you are using and unmaintained version of Slicer.
  2. Copy the files somewhere that’s not on Onedrive. Cloud synced folders can sometimes cause weird issues.

If these don’t help, you need to share the dataset.
