At 10:09 I started saving the scene, which it did successfully (a .mrb file was created which has the same size as the original), but immediately after that Slicer closed. As you see, the entire save process has not been logged. I tried to start slicer.exe several times to no avail. I my desperation, I also gave the “Recommended Windows compatibility settings” a try, but that did not help either, of course (well, there were no compatibility issues before, so I did not expect this to do much).
As before, no new log file is started during these startup attempts, and the one I pasted above is not appended, either.
The scene in question contains an MRI, two CTs and radiotherapy dose data as well as a radiotherapy structure set. I use SlicerRT for these.
I am happy to share the scene via private message if one of the developers would like to give it a try.
I briefly though that there might be some interference with other software, because one of the sudden crashes coincided with me opening R Studio, but since I have re-started my computer in the meantime and only had Slicer open this time, this can probably be ruled out.
I also loaded the scene in the old 4.8.0 installation was able to successfully save it from there without crashing. Log file: [was over the character limit for a single post, follows below]
Gonna re-install Slicer 4.10.0 now again.
Please let me know if there is anything specific you would like me try out.
Thanks
Stephan
