It seems that it is the same issue as this:

> [@Totalsegmentor showing missing threadpoolctl module](https://discourse.slicer.org/t/totalsegmentor-showing-missing-threadpoolctl-module/38452):

> hello community. I have updated my slicer version to version 5.6.2 and that seems to have broken Total Segmentor. I am getting a failed to compute results with non-zero exit status 1 with the following logs. it looks like a python module threadpoolctl is missing. My python is rudimentary, is there a way to install this manually and get total segmentor to reference it correctly? Processing started Writing input file to C:/Users/XXXX/AppData/Local/Temp/Slicer/\_\_SlicerTemp\_\_2024-09-20\_05+05+47.1…

The solution is described there.
