I don’t know how you want to get the logfiles, because I cannot attach them here directly. Please find the last lines of version 5.13 below.

I have only started the app and loaded the DICOM sequence from the DICOM database (w/o Advanced checked). After dragging the Multiphase sequence into the VR window 3D Slicer crashed with version 5.13. With version 5.11 it’s loading and displaying fine.
