Cannot download HALion Sonic 7 content - stops at 1.4 Gb

Each time I download the HALion Sonic 7 content from here - Cubase Pro 12 Downloads | Steinberg - the download stops at 1.4 Gb and the resulting disc image download is incomplete and cannot be opened.

This is on Firefox 111 on Windows 11

Edit - I can download it OK using Edge.
