I once had hopes that a trace-back log would help a support case but tech support told me it was pretty much useless without the rest of the associated files.
Corrupt files is one of the reasons you get these. I've sent corrupt files to tech support, and again, PTC could not repair them. KEEP THOSE INCREMENTAL SAVE FILES! My only recovery was to find the file that didn't crash Creo.
One of my issues was a corrupt image assigned to a datum plane (underlay BMP file). Something got completely confused and it was showing the wrong images on the wrong planes. Even deleting them did not resolve the file. I went back about 3 saves and removed the images. No more issues after that with this file.
Don't put off this investigation. When something like this happens, you have to get on top of it. Definitely make use f tech support. Every user working on a system that has maintenance should create their own support cases. Some larger companies like to funnel things through IT. Regardless, use these services, they're paid for.
