Flatseal Not Launching

[cchough]

I have Flatseal installed on my Steam Deck via Flatpak but it won't launch. I have deleted and reinstalled, and no luck. My OS details are:

NAME="SteamOS"
PRETTY_NAME="SteamOS"
VERSION_CODENAME=holo
ID=steamos
ID_LIKE=arch
ANSI_COLOR="1;35"
HOME_URL="https://www.steampowered.com/"
DOCUMENTATION_URL="https://support.steampowered.com/"
SUPPORT_URL="https://support.steampowered.com/"
BUG_REPORT_URL="https://support.steampowered.com/"
LOGO=steamos
VARIANT_ID=steamdeck
VERSION_ID=3.7.17
BUILD_ID=20251027.1
STEAMOS_DEFAULT_UPDATE_BRANCH=stable

And the error I get when launching via terminal is:

(com.github.tchx84.Flatseal:2): Gtk-WARNING **: 14:45:10.541: Creating a portal monitor failed: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface “org.freedesktop.portal.Inhibit” on object at path /org/freedesktop/portal/desktop

Thanks!
