Sketch download from web editor zip file corrupt CRC error

I am trying to download a zip file of my sketch I created with the online web editor, but the zip file which I get back seems to be corrupt as I can’t open the zip file and uncompressed the files (CRC error reported).
Tried on two computers and edge and chrome, same on all.
Files seems to be on a size to suggest date is inside, but can’t uncompress it?
Can uncompress other zip files on computer with no issues.

Any help most gratefully received

I now see that this is a reported bug as files downloaded have zero kb.

But report his here: All files in download zips are empty (have 0 bytes) · Issue #2038 · processing/p5.js-web-editor · GitHub

Hope they fix it soon.
