URGENT: Program shuts down

URL of experiment: https://pavlovia.org/run/cmfo/isiv1_s2/html/

Description of the problem: I have been experiencing problems with my tasks the past two weeks whilst when I started one month ago everything was working normally. Were any changes made to pavlovia? It is really putting me off using pavlovia again because I have been losing a lot of data. My participant just mentioned that when she does the task “i get only a bit through the program before the computer shuts down”. Another participant referred a similar concern about a different task. When I do them on my computer they work normally so I have no idea how to fix it.
The link above is only one of the tasks I have been experiencing problems with, to be honest, pavlovia seems to be giving me problems with all tasks despite them working for me.
