High CPU usage and "not responding"

[awesomeferret]

When I open Candy, it just hangs and there's a little loading wheel next to the "open video/playlist" search bar that spins. After about 5 minutes of this, the application became usable. Windows 10 1909 x86_64 EDIT: it honestly spends more time hanging than not. Usability comes and goes. EDIT2: And... absolutely nothing happens after pasting a YouTube link once the loading circle has stopped spinning and the application stops hanging. I see in the screenshots that there are video and playlist buttons to the right of the search bar, but they never once appear for me.
