This has happened with the last few patches as well. Scan and Repair doesn’t help.
The only way I have been able to successfully update the last few months has been to do a complete Uninstall/Reinstall of the game.
Notes: I use a PC with a dedicated hardline to the internet. I get 12 up, 400+ down and 9ms. I can download and install HS in a matter of moments. After months of testing and monitoring, I can assure you any issue is not something on my end or my ISP.
