PsychoPy version: 2020.2.5
Problem: I created an experiment in builder displaying pairs of random dot stimuli moving in different directions. I was able to create an experiment that worked fine on my machine, then sent it to others to test it out. Initially it seemed to be working fine, but then recently both of my testers reported that when they tried to run the experiment, it would briefly open up a blank grey screen, then close itself.
- There were no error messages.
- Both were running the experiment on Macs. However, they were both able to successfully run other experiments that I had created without any issue. The main difference is that this experiment uses the Dots component.
- I am still able to run my original experiment without issue.
I tried recreating the experiment exactly on my own computer using the same specs and components. Strangely, this actually replicated the error - when I try to open this copy of the experiment, it opens up a grey screen then closes itself. The only clue is that when I tried to export the copy to the coder to try and compare the code for the two versions, it failed. Instead, a dialog box says “Failed to open [file pathway]. Not a file.” Other than this, there are no error messages when I try manipulating the copy. The original version of the experiment is able to successfully be exported to the coder.
I have no idea what could be causing this, but if anyone has any ideas, I would greatly appreciate it!
