Broken image links and zero byte image exports

Anyone else found that upon export of your site you end up with missing images?
Looking at the images not loading it appears they’re all zero bytes.
So there’s an issue with the export.
We’e tried replacing all the assets in the asset library. Refreshed. Removed and replaced them again!
Same issue persists.
We’re using the most up to date version of Blocs. New issue?

Just further on this issue. I note we didn’t have this issue on earlier versions when we were running the file and assets of our NAS.
But now we’re on 2.4 using files that are on a networked device seems to be more problematic.
Could this be the issue with assets becoming broken links or exporting as zero byte files?
We’ll try moving everything locally and see if it changes.
