Python crashes consistently

For some reason everytime I try to run an experiment Python crashes I get the following message:

"Python seems to have crashed. This should not happen. If Python crashes often, please report it on the OpenSesame forum."


  • I had the same issue that I solved updating psychopy. Maybe it is the same for you.
    Try and let me know!

    Thanks, can I do this via the opensesame intrface? I'm trying to find it but can't..

  • Hi Eva,

    Could you provide some more information?

    • What operation system do you use?
    • What version of OpenSesame?
    • When exactly does the experiment crash? I.e. does it crash immediately, or does it first run for a while? And does it always crash at the same moment?
    • Do all experiments crash in this way, or only this particular experiment?


    There's much bigger issues in the world, I know. But I first have to take care of the world I know.

    Hi Sebastiaan,
    Of course!

    1. Windows
    2. Latest version of OpenSesame (checked for updates and then it reaffirms there are none)
    3. Yes, immediately basically on the first "instructions page" which is a form_text_display, it loads normally but when you try to click the "ok" button it crashes
    4. Yes, also experiments that first worked normally.

    Hope this helps :)

  • Ok I tried some more, I just programmed a totally new experiment that essentially worked without crashing (though I just piloted a very simple test version). It could be that since for this experiment I basically adapted an old experiment script that was programmed in a different version that it crashed?
    Also the ones I mentioned in 4. were I think originally programmed in an older version.

  • Ok somehow it works today -- guess just had to restart the pc.. always the same
