Can't try my experiment in the browser

Hello!

I'm new to OpenSesame, first of all thank you for this great program!

I'm trying to implement an experiment online, I had some inline scripts that I already converted to JavaScript, and it seems to work fine. However, when I try to run it in the browser (offline), I get an error message.

I copy here what I get (here you can't see the colors but I have in red u'standalone' and 'MemoryError'. Do you know what it could be? The dimension of my experiment is bigger than the one recommended (96MB, I have music and pictures in it). Could this be the problem?

Sorry if this is a stupid thing, but I'm quite new to programming language

Initially I thought to test participants in the lab, but due to the coronavirus restrictions I must do it online.

Thank you.
