rdt-client: Stuck at "Torrent waiting for file selection"

It seems sometimes specific torrents will hang at “Torrent waiting for file selection.”

I’ve tried the following settings:

• Only download available files enabled; minimum file size 100MB
• Only download available files disabled; minimum file size 100MB
• Only download available files enabled; minimum file size 0MB

I also tried restarting the RealDebridClient service but that did not seem to help.

I checked the logs and I found this which seems to be causing the above issue:

2021-02-08 13:41:10.874 +00:00 [ERR] Unexpected error occurred in TorrentDownloadManager.Tick
Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'System.Collections.Generic.Dictionary`2[System.String,System.Collections.Generic.List`1[System.Collections.Generic.Dictionary`2[System.String,RDNET.TorrentInstantAvailabilityFile]]]' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
