City Generator stuck at "Resource pack is downloading."

Facing issue since D5 Render 3.0 now even with latest hot fix update. I am unable to use city generator now. It just says “Resource pack is downloading” but it does not actually download, as you can see from task manager. Stays like this forever, making different selections, changing locations, or changing import filters has no effect.

There is no bandwidth activity. Which means it’s not actually downloading anything at all.
I have logged in and logged out my D5 Pro account.
Restarted computer multiple times
Started with new file
Loaded older projects

I have changed my network settings multiple times, used different wifi and wired networks. Tried different DNS settings. No effect.
