PsychoPy version: 3.1.5
Standard Standalone? (y/n): y
What are you trying to achieve?:
Our lab uses PsychoPy3 to run several cognitive tasks. In the past week, PsychoPy on 3/6 of our computers has stopped immediately running the programs, and instead takes up to 6 minutes for the first instructional screen to appear. For the 6 minute loading time, we see the grey background screen, and the program cannot be exited using the Escape key. The Builder opens normally, but the program slows to a crawl once the program is run. Once loaded, the program runs very slowly, and will frequently skip screens with timed offsets (e.g., the fixation cross will not appear before some stimuli).
All our programs were built using the Builder in PsychoPy3, and all of the computers are running the same version of PsychoPy (3.1.5 win64), so it is unclear why this issue is affecting some of our computers but not others. The program ran on all computers earlier this week, and we did not update PsychoPy in between the program running normally and the error occurring.
What did you try to make it work?: We have tried uninstalling PsychoPy3 and reinstalling.
What specifically went wrong when you tried that?: We had the same slow loading time problem. There are no error messages, it just loads and runs very slowly.
Update: We got the programs to work by uninstalling a recent Windows update (not a Security update). If other people encounter this issue, it is a quick fix. But people should look into why this error is occurring.
Can you tell which one it was? This issue keep come and go on our PC-s and it makes things very volatile…
Some have it some don’t, than it is back to normal for some reason, and then pops up again. Out of control…
Yes, more information about the fix would be highly appreciated!
We have the same problem described in the first post running the same Builder experiment on 10 PCs with very similar hardware and PsychoPy 2020.2.5 Standard Standalone. About half of them have the problem.
PsychoPy / Help / System Info only shows differences in the CPU and OpenGL info. However, both variants are featured both on working and non-working PCs, so they can’t be the direct cause.
