Dolphin freezes when opening Controller Settings

[exwii]

When I open the Controller Settings in the Dolphin main screen, the app freezes completely and has to be force-quitted.

Things I've tried to do: Resetting the config files, upgrading Dolphin versions, rebooting the computer.

If it helps, I use Dolphin 5.0-11455 on an iMac running macOS Mojave 10.14.6
