Hello  
With the new version, did you check the “PyTorch Utils” and ensure the Torch and TorchVision are correctly installed? I am not sure if you are using CUDA or not but I might not be a bad idea to uninstall and reinstall the Pytorch and then force reinstall the Python package for the TotalSegmentator.  
Please let me know if this helps.
