flatpak crashes on startup

[jackaperkins]

Hi, i just installed rcloneUI flatpak on Fedora Linux 43 and it crashes instantly on startup. I see a short flash of a window and then it's gone with no message. This is the regular flatpak from flathub, no fedora flatpak weirdness

here's output from flatpak-coredumpctl com.rcloneui.RcloneUI
