Thanks for the feedback. Please try V 1.0.3 found here in GitHub releases. Let me know if that works. If not, please attach a troublesome S file to a comment.
The new version 1.0.3 doesn't crash, but it fails to import the file as well. Here is a very abbreviated Touchstone 2.0 file:

Also, version 2.0 files usually have an extension of .ts rather than .snp. Your open dialog should include .ts files if you think you'll support version 2.0 files.
S2SPICE v1.0.1 crashes when trying to open a Touchstone version 2.0 file. Converting the file to version 1.1 works fine. Since the differences between the versions are mainly helpful comments and summaries, should S2SPICE ignore the comments and summaries or use any that are useful, such as 2-port data order and mixed-mode order?
