cannot change the configuration file via ui

When I open the settings and click on the configuration file, the software center crashes

thread 'main' panicked at 'The runtime of the component was shutdown. Maybe you accidentally dropped a controller?: Open', /build/nix-software-center-0.1.1-vendor.tar.gz/relm4/src/channel/component.rs:66:34
