OSWeb experiment only working on some PCs
My experiment seems to only work properly on some PCs when running it through OSWeb. Sadly, it doesn't run properly (or even at all) when I try to run it on my PC (nor it does on a lab mate's PC). When executing the experiment on OSWeb it goes straight to a blank screen after the first OSWeb logo screen.
Surprisingly, it does run properly on two other lab mates' PCs. I thought this has something to do with refresh rate but trying to change the duration to different values (470 instead of 500 or 995 instead of 1000) didn't help. For reference my display rate is 59.997Hz, and my lab mate's PC's refresh rate is 60.010Hz (the experiment does run on that PC).
Another idea was that something in browser is faulty because of some errors in the browser's console (see attached picture).
I'm using OpenSesame 3.3.7, OSWeb 184.108.40.206 an up-to-date Chrome browser v88.0.4324.182.
