spotcast: Spotcast can't find Spotify integration even if it's installed

Describe the bug After installing the latest release (v. 3.1.18) the integration is not loaded with the following errors:

2021-10-31 15:22:33 ERROR (SyncWorker_1) [custom_components.spotcast.helpers] spotify integration not found
2021-10-31 15:22:33 ERROR (SyncWorker_1) [custom_components.spotcast] Spotify integration was not found, aborting setup...
2021-10-31 15:22:33 ERROR (MainThread) [homeassistant.setup] Setup failed for spotcast: Integration failed to initialize.
2021-10-31 15:22:33 ERROR (MainThread) [homeassistant.setup] Unable to prepare setup for platform spotcast.sensor: Unable to set up component.

It seems spotcast is not recognizing the spotify integration regularly installed as you can see:

and also from /.storage/core_entity_registry it is completely loaded:

            {
                "entity_id": "media_player.spotify_mfabiani53",
                "config_entry_id": "xxxxxxxxxxxxxxxxxxxxxxx",
                "device_id": "xxxxxxxxxxxxxxxxxxxxx",
                "area_id": null,
                "unique_id": "mfabiani53",
                "platform": "spotify",
                "name": null,
                "icon": null,
                "disabled_by": null,
                "capabilities": {},
                "supported_features": 0,
                "device_class": null,
                "unit_of_measurement": null,
                "original_name": "Spotify mfabiani53",
                "original_icon": "mdi:spotify"
            },

When reverting back to the 3.1.17 release all is working ok ! I am trying to use the using latest version of spotcast v. 3.1.8 I am using latest stable version of Home Assistant
