How to cast object to Func

public static class PropertyAccessor
{
    public static Expression Create<T>(string propertyName)
    {
        var property = typeof(T).GetProperty(propertyName);
        if (property is null)
        {
            return null;
        }

        var result = typeof(PropertyAccessor).GetMethod(nameof(CreateExpression))!
            .MakeGenericMethod(typeof(T, property.PropertyType)
            .Invoke(null, new object[] { propertyName });
    }

    private static Expression<Func<TIn, TOut>> CreateExpression<TIn, TOut>(string propertyName)
    {
        var parameter = Expression.Parameter(typeof(TIn));
        var body = Expression.Property(parameter, propertyName);
        return Expression.Lambda<Func<TIn, TOut>>(body, parameter);
    }
}

I'm tried to cast using Convert and other things, but without knowing TIn and TOut in compile time it's unable to cast
