With the latest release 1.13.0 the admin page upon login fails to render with:

This was found in our Cloudron app package test pipeline and after looking through the changes, maybe there is a missing (string) cast at https://code.castopod.org/adaures/castopod/-/blob/fc0001c3522e250a693b3e9d9da2a0de15bfbabc/app/Views/Components/DashboardCard.php#L35 which was overlooked in that change fc0001c3

I might be overly wrong, as I am no php expert at all. For any other hints I am also thankful.
