Error: IS-FC06 while trying to download UE5 on Mac OS

Trying to download UE5 but after some download time it says “a file corruption has occurred” and gives me the error code IS-FC06 and tells me to try again. I have with no luck. I’m on a mac with OS Catalina installed and a 3,2 GHZ processor and enough free memory and space at around 120 GB. Trying to google help but all I can find is for PC.

Can you please help?
