Eventually control comes back > to Emacs but that might be due to repeated presses of C-g. This could be due to the fact that Emacs 26 uses async communications more than previous versions. Does gnus-group-get-new-news use any of the url-* functions? If so, perhaps try setting url-asynchronous to nil when fetching news, to see if that solves the problem. Or maybe even build Emacs with HAVE_GETADDRINFO_A undefined, and see if that helps. (I'm not saying that these should be the solutions for this bug, just that they might tell us whether the asynchronous communications features are involved here.) I think it would also help stepping through the failing functions with a debugger and seeing which parts of them fail. Thanks.
