I have the same problem with Rhino 8 on a Dell Laptop XPS 13 9305 since recently. In the past few years the Package Manager has always been installed an accesible. There is an error message saying that the packages cannot be fetched from the yak yource. This seems to be a “new” problem. Can we get help, please.

At home, I created some small plugins locally, and I think that might be the cause; perhaps installing one of the plugins modified a core Rhino file, but I don’t know how to verify that. I have two computers with the same plugins, but I only have this problem on one of them.

I’ve had the same problem for a few weeks now. I think it’s related to my Rhino locking up when I do: Tools → Options → Updates and Statistics. Dale’s link above works in my browser.
