Unable to generate a URL for the named route "ransomwaredetection.page.index" as such route does not exist.

I removed the app after seeing the warning about all the files deleted.

I've just upgraded to Nextcloud 18.0.12.

In case it helps, I was never been able to have the app running. It always showed an empty page with the loading icon. But nevertheless, I still kept this app on my Nextcloud instance, in case it started working one day (until today when I disabled it). The app frequently generated error messages in Nextcloud log. Here are those I got before disabling it:
