Why would I get an "Invalid Cast" with this code?

like below fixes the issue The foreach will try to cast the control to the specified type which will give that invalid cast exception, what you should do is:
code :
foreach(Control ctrl in this.Controls)
    if(ctrl as TextBox != null)
         //Textbox logic
    if(ctrl as ComboBox!= null)
         //ComboBox logic

I wish this helpful for you My guess is you don't have quotes around @dateTimeParam in query, and query parser assumes it is an int.
What really bugs me though is why you surround parameters by quotes at all.
code :
var command = new SQLiteCommand (
   "INSERT INTO DATAOUT (id, uid, application, eventname, clienttoken, version, datetime, data)" +
    " VALUES (@idParam, @userIdParam, @applicationNameParam, @eventNameParam, @clientTokenParam, @versionParam, @dateTimeParam, @dataParam)",
var command = new SQLiteCommand (
    "INSERT INTO DATAOUT (id, uid, application, eventname, clienttoken, version, datetime, data)" +
    " VALUES (@idParam,@userIdParam,@applicationNameParam,@eventNameParam,@clientTokenParam,@versionParam,@dateTimeParam,@dataParam)",

command.Parameters.AddWithValue("@idParam", insertData.ID);
command.Parameters.AddWithValue("@userIdParam", insertData.Uid);
command.Parameters.AddWithValue("@applicationNameParam", insertData.Application);
command.Parameters.AddWithValue("@eventNameParam", insertData.EventName);
command.Parameters.AddWithValue("@clientTokenParam", insertData.ClientToken);
command.Parameters.AddWithValue("@versionParam", insertData.Version);
command.Parameters.AddWithValue("@dateTimeParam", insertData.DateTime);
command.Parameters.AddWithValue("@dataParam", insertData.Data);

I wish this helpful for you I think your problem is the version itself. Check Mongo is throwing a syntax error due to "$geoIntersects" doesn't exist, it was changed from $intersects to $geoIntersects so I would try to run the same code using:
code :
s.find( {shape: {$intersects: {$geometry: BOX}}}, {_id:1})

To fix the issue you can do In this context the ExecuteScalar returns a System.Int64.
Applying the (int) cast creates the exception you are seeing
code :
object result = cmd.ExecuteScalar();
Console.WriteLine(result.GetType());  // System.Int64
SQLiteCommand cmd = new SQLiteCommand(qry, con);
count = Convert.ToInt32(cmd.ExecuteScalar());

I wish did fix the issue. I have seen the same issue happened and the latest news I got from support team is: Problem was identified ; due to recently introduced defect some published models were removed ; after which prediction requests against these published models would fail. The original bug was fixed and a repair program was ran that put back the missing published models. So I think your issue should be fixed now as well. If not, please let us know. Thank you.
