Hi Jibroni,
Thanks for submitting this feedback, I appreciate it!
Some earlier versions of 5.27.x had export bugs, but to the best of my knowledge most of these should be resolved with 5.27.9:
https://www.pingplotter.com/download/release-notes/I've just ran through this functionality on my instance of PingPlotter and didn't run into this crash. We have released 5.27.10, I suggest trying this first to see if that fixes things for you (Help > check for updates).
With that said if you do continue to experience issues/bugs/errors could you submit a support request from inside PingPlotter (Help > email pingplotter support)? This will send us some diagnostic logs that will give us a much better look into what could be causing this.
All the best,
-TJ
