Problem opening task

PsychoPy version (e.g. 1.84.x): v2022.1.1
Standard Standalone? (y/n) If not then what?: y
**What are you trying to achieve?:

I am trying to open the task I have made. I made the task on an older version of psychopy, but when I try to open it on another computer that has the latest 2022 version, but I am getting the attached error.

I’m not sure what to do because I have another task that is identical but uses different stimuli, and I am able to open that on my computer with the new version and run it fine. I also have a third task that uses the same stimuli as the current task I cannot open (but is different in other ways) and that can be opened and run as well.

I’m very confused because I can’t see how this particular task is a problem, and I’m having trouble understanding the error. I’d really appreciate any help. We are hoping to start testing soon, and I really need to get these tasks running.


I would recommend upgrading to 2022.1.2

At what point do you get the error? When you open the file locally or when you try to sync? It might be worth trying to sync it from Pavlovia to a new local folder. If it doesn’t yet exist on Pavlovia, then perhaps the issue is that you created a copy of your local files without deleting the local .git folder pointing to a previous experiments.


Thanks so much for your reply. I am getting the error when I try to open the Psychopy file locally. The file is just on my desktop, with all the experiment materials in it. But when I double click, or right click and try and “open with psychopy”, I’m getting this error.


I avoid saving files to my desktop. Is it at least in its own dedicated folder?

Yes, I have a folder on my desktop and in it is the task file, and all the materials that Psychopy needs to run the task. However, when I try to open the task file, I get the error.

I’m confused because that is exactly how my other task is also set up - in a different, separate folder on the desktop, and when I try to open that task file, it opens and runs fine.
