nikitazep 2.49 GiB exceeds maximum download size 1.86 GiB
This is normal. There is probably a ~ 2GB limit in your browser for downloading, at least directly into the browser. Your only other option is to assign 'download_dir' => 'zip', but there is no way your server will be able to create this size zip files without timeout or insufficient memory.
The problem is, I can't make something possible if it's not possible through neither your browser or your server.
