Crashing at the end of run and does not make csv and psydat files

OS Win7
PsychoPy version 2

I am having a problem with my script crashing at the end of the run. I have not had this problem before with this specific task, but today when I ran it four different times, the routine would go to completion and then become unresponsive and I had to force quit out of it. After I ran the experiment I noticed that it did not create the csv or psydat files. Additionally the log file cuts off slightly before the end despite the task displaying the final message on the screen. Any help with this would be greatly appreciated.

Hi @Altekrusewc, would be useful to know which version of PsychoPy are you using?

Hello,

Will is at an interview today but I checked the version. It is v 1.84.0. Thanks for your help.

I am using v 1.84.0.
