On the latest Pop_OS (24.04, with Cosmic desktop environment), the cook sync appimage starts fine, but fails to open links in browser. It seems to have an issue with xdg-open (which works fine when called from a terminal on its own).
If I paste the authentication URL in my web browser manually, I get to the authentication window, but the process fails to complete (it tries and fails to redirect to a local address: 127.0.0.1:42323).
