Critical Error - please help

I posted this 12 days ago but no response…anyone…???

Hi I’m using firefox on windows 10. I have the latest version of js.node installed.
Last week my code and scene opened fine using “DCL Start” but this week I am getting the following error (see attached screenshot).
Any ideas ?
