Radzen DataGrid issue when reloading a state from Cosmos DB

I have saved a grid state in the cosmos db and I want to load that state from that db.But this error occurs.

Error: System.InvalidOperationException: Unable to set property 'Value' on object of type 'Radzen.Blazor.RadzenNumeric`1[[System.Nullable`1[[System.Int32, System.Private.CoreLib, Version=8.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]], System.Private.CoreLib, Version=8.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]]'. The error was: Unable to cast object of type 'System.Int64' to type 'System.Nullable`1[System.Int32]'.
 ---> System.InvalidCastException: Unable to cast object of type 'System.Int64' to type 'System.Nullable`1[System.Int32]'.

Then I checked your Blazor DataGrid Component - Save / Load Settings | Free UI Components by Radzen example and it uses System.Text.Json deserialization. It gives FilterValue for a column as JsonElement like this.

ValueKind = Number : "1"
    ValueKind: Number
    _idx: 0
    _parent: {System.Text.Json.JsonDocument}

But when we retrieve FilterValue from cosmos db state it gives Int64 1.
How to handle this?
