Unspecified JavaScript error: works in some computers but not others

FYI, I think the error you all are discussing here is the same or at least related related to the one that I raised in this thread.

EDIT: I initially thought that my work computer’s Chrome and Edge were throwing the same error, but now I don’t think so. I tried to run this very simple test experiment https://gitlab.pavlovia.org/atryan/migt-v1-05 and it worked, so it really does seem to vary from computer to computer.
