Editor three.js : Render function no longer exists to create an MP4 file

since 2 days, Render function no longer exists in Editor three.js ( project section),
at the end of the realization, I used it to create an MP4 file.
is it a Bug or do I have to do something else to create it?
knowing that I only use Editor via firefox and chrome

As mentioned in Why FFMPEG is used? - #2 by Mugen87, the browser has to support SharedArrayBuffer. It’s possible that a browser update removed the support for security reasons.

it’s strange, same problem on MacBook Pro - Apple

I find that the editor is very well done and I am not a programmer
do you know how to update the browser or some other solution to create MP4 when the Json is published ?
