ffmpeg.wasm Unhandled Runtime Error ReferenceError: SharedArrayBuffer is not defined

[PacoH]

After many false starts, following your incomplete install instructions (you omitted cd gif-maker), installing the latest brew version of node and fixing all the npm issues, I finally was able to run the development server. When I did I got this error in Chrome 106.0.5249.91:

Unhandled Runtime Error

If I can't fix this I give up.
