OS: Win11
PsychoPy version: 2023.2.3 Py 3.13
Standard Standalone Installation? yes
Do you want it to also run online? no
What are you trying to achieve?: install Advanced Vision Science plugin on PsychoPy version 2023.2.3
What did you try to make it work?: too many things: installing from windows console, adding the program file from another computer that is already installed in the same version, tried to install PsychoPy from pip…
Link to the most relevant existing thread you have found:
What specifically went wrong when you tried that?: I think that this PsychoPy version (and probably some others) is not receiving data from Pavlovia or syncing correctly with PsychoPy server. The program shows me this issue when I try to install from Tools → Plugin/packages manager:

Upgrading to a newer version is not a viable option, as I have developed a large experiment using that version, and all lab computers have it installed.
It’s very strange because just a few weeks ago (around four), I was able to install that plugin on another Windows computer using the same PsychoPy version, and now the same error is appearing on both machines.
