Open3D hasn’t been used in ALPACA for over a year now. Version in the current stable (5.6.2) uses ITK libraries and that’s what is trying to download.

All your errors are certificate errors, meaning your computer cannot download files due to incorrect certificates. This can happen in networks with tight security settings and firewalls with self-signed certificates.

Is there another connection you can try, a public wifi perhaps?

You are not displaying the whole log file, so I can’t tell what’s the “issue”. I suspect it is the same as before SSL certificate issue. The only solution to that is to try on another network.

If you cannot find a working network, you can try to download this zip file. It should have all libraries for ALPACA already loaded in it. Unzip, and launch Slicer from that folder.
