Radzen scheduler takes time to load

Can you test the suggestion from this github issue? Add this code somewhere in your app so it executes at startup:

class MyCustomTypeProvider : IDynamicLinkCustomTypeProvider
{
    static readonly HashSet<Type> empty = [];
    public HashSet<Type> GetCustomTypes() => empty;
    public Dictionary<Type, List<MethodInfo>> GetExtensionMethods() => throw new NotSupportedException();
    public Type ResolveType(string typeName) => throw new NotSupportedException();
    public Type ResolveTypeBySimpleName(string simpleTypeName) => throw new NotSupportedException();
}

And then in Program.cs do this:

System.Linq.Dynamic.Core.ParsingConfig.Default.CustomTypeProvider = new MyCustomTypeProvider();
