Can't Download Table B01003 (5 YR 2018 ACS) for All ZCTA's

On I'm trying to download table B01003 5 YR 2018 ACS data for all ZCTA's.  

I've tried this multiple times with different browsers. This continually hangs and then a browser popup appears suggesting to end the script.  I can download this table successfully for other geographies.

Are you aware of this problem or can suggest a work around?

Thanks for any help
