The most interesting thing is the crash disappears when I add a line print('1') before _getPluginAndLoadableForFiles.

3

Could you please test if you can reproduce this on the latest Slicer Preview Release?

5

not useful. Although I successfully run once a time, after that, I still get into crash.

6

Do you have any problems if you load the images using the DICOM module GUI?
Does it help if you change the DICOM reader approach in menu: Application Settings / DICOM?

If you need help with investigating the problem, please provide a minimal example (as short as possible, remove all parts that are not necessary for reproducing the crash) and corresponding data that reproduces the issue. If the problem is not reproducible with publicly available DICOM data sets then you would need to share an example data set, too (remove all patient information; you can also blank out the image data).
