I am experiencing an issue with the "Split Line at Vertices" tool when using it within ModelBuilder. Specifically, the tool fails when connecting the input variable, and ArcGIS Pro shuts down afterwards.
Thank you for your help in resolving this issue.

featureclass in a geodatabase? on a local drive?
shapefile?
multipart or singlepart?
Can you use the tool outside of modelbuilder on the same fgc without issue?
