This <u>[recent post](https://sqlite.org/forum/forumpost/50a6f798876b5a18?t=h)</u> describes a problem created by an MSBuild change which I suspect has led to your issue. Either getting an MSBuild update or manually specifying another target to get SQLite.Interop.dll copied should function as a work-around. Or you could just copy the DLL yourself until that update is generally available.
